I think it's time Angle got a new finish, personally. Although, honestly, there are only three finishes in WWE that are still pretty protected: Pedigree, Tombstone, and Stunner.
I'd like to see Angle do some sort of Blood Rush (see "Wrestling Moves discussion" post in the General Wrestling folder for description, 5th post up from the bottom), as it'd be fairly easy to hit on people of equal size, as well as a little bigger. And for the hosses? AnkleLock works fine.
Can anybody think of a great finish these days, indy or puro or otherwise, that doesn't involve a head-drop? Aside from a few cool flying moves, and maybe a great submission here and there, nothing really comes to mind.
