Is this an infinite size interaction RAW?

[God/Dog]

Greetings people, i've been looking for an infinite size combo that i could use to make a massive character, beyond colossal.

I believe i found one that works RAW and i would like your opinion.

As the title says the interaction only works RAW and it's obviously unintended for a character to increase in size indefinitely, so please let's have this in mind during the conversation.

The basic idea here stems from how Disguise self works when paired with Enlarge.

If you use Disguise self you can only appear as a creature of your size, but if you cast enlarge you can appear as a creature of a size bigger than yours. Then you can decide to dismiss enlarge and you are still left with a large disguise, this is the basic principle that i'll be using.

For the combination we need 2 levels in Vigilante with Malleable Flesh and 1 size increasing effect of our choice.

Malleable Flesh (Su) (Chronicle of Legends pg. 7): Whether through mutation or alchemy, some vigilantes have flesh that is as moldable as clay and as fluid as ink. A vigilante with this talent gains the shapechanger subtype and the compression universal monster rule. In addition, the vigilante can alter his appearance as disguise self, except that the changes are physical rather than illusory. However, aspects of the vigilante’s aesthetic persist in all forms, halving the bonus on Disguise checks gained from this effect and from seamless guise. At 12th level, the vigilante can pass through narrow openings, even mere cracks, along with any item he wears or carries (to a maximum of his light load).

The big difference here is that Malleable Flesh is not illusory, your character truly becomes one size larger and this allows the pc to repeat the process indefinitely until a satifsying size is reached since the character is not under any spell increasing it's size or polymorph effect.

Would this be a viable solution to bend the existing rules of the game into realizing my concept wihout the need of any kind of homebrew?

"but if you cast enlarge you can appear as a creature of a size bigger than yours. Then you can decide to dismiss enlarge and you are still left with a large disguise"

No, if you dismiss the enlarge you can't keep the large size disguise. the same way that losing any prerequisite make you unable to use the effect that require it. lowering your str below power attack requirement mean you can not use power attack for example.
the disguise allow a larger form only when enlarged. dismissing the enlarge make the larger form 'shrink' the same as would happen to anyone who has enlarge on him and have it dismissed.

Why can't you?

I haven't seen any rule specifcying it but read about the Shillelagh Precedence stating the opposite.

But the Shillelagh Precedence doesn't fit perfectly in this case since it's related to what happens when you don't meet the spell requirements anymore but in these case he requirments are met.

The rule're talking about is for feat requirements, nothingin the Disguise self spell says the effect is not sustained if your shape changes.

Rueles as written it seems to me that you could even polymorph into a huge creature while holding a disguise self spell active that makes you look like a medium orc.
Even if the huge form would make the disguise useless it would still be active.

because the size change comes from the enlarge spell, once it's gone the size change can't be maintained the same way not having enlarge to begin with stop you at medium size.

the disguise spell say:
"You can seem 1 foot shorter or taller" the enlarge is what let you disguise bigger because you are bigger.
Once it's gone the disguise has to keep up on it's own rules in which "You can seem 1 foot shorter or taller" now you are back to medium so your disguise can't be more then 1 foot taller.

"Enlarge person" is the effect that make you one size larger
"Disguise self" is the effect that disguise your appearance

If you are enlarged, the "disguise self" disguise you as the larger one, if the enlarge effect end, then your size is reset, and the "disguise self" will not maintain the enlarge effect.

"You can seem 1 foot shorter or taller, thin, fat, or in between."

If not, then you are using the "disguise self" to seem more than 1 foot taller while you are actually a medium size character.

Disguise self makes 1 one foot taller of the size you were when the spell is cast, unless there is a specific rule that says the "abilitating" effect has to remain always active for the rest to not dissipatethen the large disguise is still active even without enlarge self.

The rule exists for feats for example, but i've never seen it for spells and making the rule up is not RAW.

[zza ni]

the rule was brought for feats as you mentioned but it was also used for prestige class not having their requirements.
it's a general rule not just for feats.

any effect that has requirements that lose these requirements can't keep it's effect (unless mentioned specifically that it can).

in this case, say you cast enlarge person then disguised as an ogre. dismissing the enlarge will shrink you as this is the effect of dismissing said spell, you will show up as an ogre who was hit with something like reduce person -a medium sized ogre.

[Bureau of Managing Expectations]

If a medium creature casts enlarge person and picks up a large weapon, they can wield it without penalty. If they continue wielding the weapon but dismiss the spell, then . . .

we can stop there as you've gone off the rails I've bolded where you went wrong. The spell effects do not work that way for Disguise. Essentially the two spells; Disguise Self:I1, Enlarge Person:T1 are separate effects. You are trying to make them mundane real objects rather than magical spell effects.

Read up on illusion, glamer, and polymorph in the arcane school descriptions. Reread the spells again paying attention to what they do.

You can cast disguise self to appear to be your brother (keeping it simple), a medium sized humanoid(human) type. Then cast enlarge person to become a large sized humanoid(human). When the enlarge wears off you revert to medium sized humanoid(human) looking like your brother (assuming disguise self is still active).

Can you doff the clothes of disguise self? sure but they would revert to your original clothing before you cast the disguise self once separate(not your possessions), it is just a glamer, see invisibility about dropped objects. Spell Target is "you", not your clothes or weapons.

If you are proficient with greatsword or heavy crossbow, then when enlarged you can use a large greatsword or large heavy crossbow without a inappropriate size penalty as it is sized for you. Using a large sized heavy crossbow is an old trick before the days of Gravity Bow.

Magical size alterations are heavily monitored in the game and they scale up in level rather quickly. There are a couple of tricks via some broken magic items or magic jar.
