Can you stack a Cloak of Human Guise with a Hat of Disguise?

Cloak of Human Guise

Spoiler:

Cloak of Human Guise
Aura faint illusion; CL 1st
Slot shoulders; Price 900 gp; Weight 1 lb.

DESCRIPTION

This plain cloak only has any effect when worn by a member of a half-human race, such as a half-orc or half-elf. It alters the wearer's appearance similarly to a hat of disguise, but only to the extent that it conceals or alters the wearer's non-human physical traits so the creature appears fully human. Any feature that is plausibly human remains. For example, a half-orc wearing the cloak loses his green or gray skin color and pointed ears, has no visible tusks, and is otherwise completely able to pass as a human version of his normal self. Likewise, a half-elf wearing the cloak has round ears, human-like eyes, and no other traits indicating elven ancestry. The wearer has no control over the specific guise, and those familiar with his normal appearance can recognize him in his human guise.

Hat of Disguise

Spoiler:

Hat of Disguise
Aura faint illusion; CL 1st
Slot head; Price 1,800 gp; Weight —

DESCRIPTION

This apparently normal hat allows its wearer to alter her appearance as with a disguise self spell. As part of the disguise, the hat can be changed to appear as a comb, ribbon, headband, cap, coif, hood, helmet, or other headwear.

CONSTRUCTION REQUIREMENTS

Craft Wondrous Item, disguise self; Cost 900 gp.

Both say that they provide you with a +10 bonus to your Disguise checks, BUT the bonus is untyped. That is why I am wondering if multiple items stack since the one claims to work "Similarly" to hat of disguise.

I don't think this works since the bonuses are from the same magical source, but they come from different items AND more importantly are untyped which typically allow stacking.

Answers are appreciated.

I don't see why Cloak of Human Guise even mentions that it works like Hat of Disguise since the effect is very different.

Hat of Disguise grants unlimited uses of Disguise Self per day (so you have to keep re-activating it). Disguise Self grants a +10 bonus on Disguise checks and can be used to change your apparent height, weight, race, gender, age... pretty much anything a Disguise Check can change, just as a Standard Action and with a +10.

Cloak of Human Guise basically automatically succeeds a Disguise check that already has a +3 modifier (+5 minor changes, -2 different Race). It really doesn't work like a Hat of Disguise or Disguise Self AT ALL, since both of those let you majorly change your appearance. The only way it's like a Hat of Disguise or Disguise Self is that it doesn't physically change your appearance, just what people see.

As to the question if you can stack them, I don't think you can, since they come from the same source (Disguise Self spell), but you might be able to argue with your GM that it negates the -2 penalty for disguising yourself as another race.

Only the Hat of Disguise gives you a bonus to disguise checks. The Cloak of Human Guise simply turns you human looking, there are no rolls involved.
So you could use the Cloak to turn into a human and then use the Hat to alter the human disguise to your specification with a total of +10 bonus to disguise. The result of this would basically just be to eliminate the -2 Disguise penalty for disguising as a member of a different race. Probably not worth it to stack them, just get one or the other.
