I made this more than a year ago based loosely on the 3rd edition Master of Many Forms. Worked out the design over the course of several months, but never got around to making it public. Made a couple recent tweaks, since there are now published versions of spells I originally had to homebrew.

Transformation (SU)
As a Morphic Master, you can assume the form of another creature. This change functions in a manner similar to the listed spells from the Transmutation (Polymorph) subschool, except where modified by other class abilities.
Available forms are listed in the Transformation Options column of the Morphic Master class table.
This ability (and any abilities tied to it) may be used a number of times per day as listed in the changes/day column of the Morphic Master class table.
Morphic Speech (EX)
You can emulate speech regardless of your physical form. This allows both communication and use of verbal spell components. You qualify for the Natural Spell feat, even if you do not meet the normal prerequisites.
Morphic Equipment 1 (SU)
If you transform into a creature with a body shape similar to your own, you can choose to continue wearing your equipment rather than absorbing it. Your equipment will resize to fit the new form. If your new form has extra limbs, temporary gaps will open in your equipment where these limbs connect to your body; this does not damage the equipment. All of your equipment is affected in the same manner.
Bolstered Body (EX)
While using Transformation, you gain an ability score bonus equal to your Morphic Master class level. If you assume a form that is Medium or larger, this bonus applies to Strength. If you assume a form that is Small or smaller, this bonus applies to Dexterity. This stacks with any other applicable bonuses.
Quick Change (Move)
You can use your Transformation ability as a move action.
Persistent Form 1
Your transformations now last longer. When you change shape, you may remain in your chosen form for up to ten minutes for each of your class hit dice. (All classes stack when determining the duration for this ability.)
Morphic Equipment 2 (SU)
When you transform, regardless of your assumed shape, you may choose to either absorb or continue wearing your equipment. This decision applies separately to each piece of equipment you are wearing when you transform. Equipment will resize and reshape to accommodate the new form, including modified or extra limbs.
Shapechanger Subtype
You gain the Shapechanger subtype. This applies to your natural form and all assumed forms. You can automatically resist any transmutation effect that would change your physical form, unless you choose to accept it.
Recover (EX)
Any time you rest for one hour, you recover one use of your Transformation ability.
Quick Change (Swift)
You can use Transformation once per round as a swift action at any time during your turn. Additional transformations require a move action as normal.
Persistent Form 2
Your transformations now count as both EX and SU. While transformed, you may choose to remain in your current form even if exposed to an effect that would normally end or suppress it, such as an antimagic field. Such conditions still prevent you from assuming a new form. If using Morphic Equipment, the equipment remains. Other supernatural or spell-like abilities are still affected as normal.
Gargantua (EX)
If you could normally assume the form of a Huge creature of a type, you may instead assume the form of a Gargantuan creature of that type. Gain the adjustments listed for a Huge size creature, with an additional +4 to Strength, +2 to Constitution, and +4 Natural Armor.
If you could normally assume the form of a Large creature (and no spell grants access to a huge creature of that type), you may instead assume the form of a Huge creature of that type. Gain the adjustments listed for a Large size creature, with an additional +2 to Strength, +2 to Constitution, and +2 Natural Armor.
In either case, size modifiers apply for the assumed creature size.
Blended Body (SU)
Through constant transformation, you have learned to blend the best traits of different forms. Once per day, choose one of the options below. Regardless of the forms you assume that day, gain the benefit of the selected option each time you transform.
¤ ABBERATION: Gain blindsight to 30 feet.
¤ BEAST: You gain a set of wings that work in both water and air. Gain a fly speed (average maneuverability) and a swim speed, both equal to twice your base speed. You can breathe both air and water, regardless of your form, unless prevented from doing so by another effect.
¤ ELEMENTAL: Choose one energy type. Your natural attacks deal 1d6 damage of that energy type, in addition to any other damage. If you would normally be vulnerable to that energy type, lose that vulnerability; otherwise you gain resistance 20 to that energy type. (Energy resistance does not stack; highest resistance applies.)
¤ HUMANOID: All of your limbs are prehensile and can wield weapons. A limb cannot be used for movement, speech, or natural attacks while it wields a weapon or holds an object, unless the object is 4 or more size categories smaller than you. Only one limb can be considered a primary weapons hand; all other limbs are treated as off-hands when wielding weapons.
¤ OOZE: You can squeeze through any space, regardless of your size. While occupying a space where you could not fit or squeeze without this ability, your movement speed is reduced to 5 feet per round, and you lose your dexterity bonus to AC (if any), in addition to the normal penalties for squeezing.
¤ PLANT: You are immune to critical hits, precision damage, and damage to your physical ability scores. (Existing ability damage remains.) Gain fast healing 1.
