Feats for Aspect and Greater Aspect

[Epic Meepo]

Would it break the summoner class if there were feats that allowed a summoner to take more evolution points than normal from his eidolon using his aspect and greater aspect class features?

Discuss.

[Quandary]

It would obviously hinge on how many Evo points they grant and any Level Requirements for the Feat :-)
But I don't see how it's fundamentally different than Improved Familiar, Extra Rage or Extra Channel (etc).

...I could also see Feats allowing access to Evo's normally available only to other base Forms (i.e. "Heteroform Eidolomastery: Choose one base form: Your Eidolon also counts as having this base form for purposes of Evolution requirements, in addition to their normal base Form. Any specific requirements (limbs, etc) must be paid for with Evolution points.")
