It wouldn't surprise me at all. Amora is known for assuming human identities. Gwen Stacy is a indentity she created for herself to learn how humans tick. Whose to say that George Stacy didn't adopt Gwen as his own child. I like to think that Gwen's death was a deliberate act to mentally break Spider-Man/Peter Parker as she desired to move on. Thus being killed by Norman Osborn was part of Amora's manipulation tactic. Do you agree that Gwen is really Amora?
