I have no idea if Remender is thinking of this, but just before Stan Lee left "Avengers" he seemed to be setting up a storyline (in that book and "Thor") where Wanda and Pietro might turn out to be not mutants, but products of the High Evolutionary's experiments.
Avengers 30:
Thor 134:
No one ever returned to this idea, though the lights on the mountaintop were later used as the basis for the Chthon story. But it is there if someone wants to return to it. We'll see what ol' Evolutionary is up to.
I hope this at least means we get to see Bova (I know she may have died in New Warriors recently, but that doesn't mean much).
