Think about it.
The secret invasion allows for any character to be returned whole (perhaps alive from presumed dead) and intact without any baggage from previous storylines. Hank Pym never created Ultron or hit Jan, Skrull Pym did that. The last thing Pietro remembers is being in the Savage Land- he never married Crystal, never went insane or evil about a half dozen times. Pym and Quicksilver could be returned to pristine quality. What an amazing tool to be able to utilize to restore characters to previously unrestorable and unforseeable greatness.

the aforementioned Quicksilver and Yellowjacket
Cap (of course)
If you were in the planning room at Marvel, what event or character development would you like to see erased.
As you could probably guess, I'd like to see Pym's and Pietro's history unwritten and rewritten.
I kind of hope they don't erase what has been happening to these Avengers and start anew ala OMD. Leave OMD-like plot with Spidey. However, it seems that the SHRA might get repealed after the story arc after Bush is revealed to be a Skrull!
Maybe Tony Stark will become IRON MAN: president of the USA! I believe there was a storyarc or two in Exiles about this one.
The big rumor I heard was that New and Mighty will be recombined for Avengers starting at #504. But that is a rumor I heard from other boards. No evidence to support it, yet.
