Sizeshifter
You can grow or shrink your body size.
Prerequisite: Eidolon
Benefit: As a standard action that provokes an attack
of opportunity, you can alter your size between Small,
Medium, Large, and Huge if you have those evolutions.
Special: Bonuses and penalties granted by any size
evolution are lost when you adopt a different size using
this feat.
I'd like this feat to be allowed. I'd also consider removing the small aspect since I can't find anything concrete on small Eidolons. Maybe you could make custom mutations at two evolution points with another three for tiny. Sort of the opposite of the Large/Huge version. Could possibly also make this a bonus feat or house rule since you do loose benefits and take an AoO if used in combat. Though it's fine if I have to burn a feat for it down the road.
