well the one good thing about pulling her out of a tank would be that if people revolted to much then they could just declare her a clone.
It might also allow the Stacy kids to come back. Make it Gwen's clones who had them. It lessens the damage to the real Gwen Stacy's character because she's not quite a perfect duplicate. And maybe their hyper aging could be explained with their father has this crazy serum pumping through his blood and their mother was a clone so they weren't really normal
I will say one thing. It takes a lot of balls to use one of the most reviled storylines ever to undo one of the most iconic moments in comic's history.
