WalterKovacs pointed out how a lot of "generic" powers already exist.
I also groove on the "advanced racial powers" and Sabathius's suggestion for skill-specific utilities, though both would presumably require taking those instead of your normal class powers, which could end up leading to some accidental suck unless those advanced racial powers or skill-specific utilities broke down along role lines (so that dwarf strikers look different than dwarf defenders, and so that controllers who know History are different than leaders that know History)....that can eat up a lot of pagecount if you don't want to look like you're favoring one or the other.
