If they do that now, it'll have to be a retcon, because it was pretty explicitly stated in Mighty Avengers that Loki had taken on the persona after the "alliance" with Osborn, because he (er, she then) thought a "personal set" of Avengers had the potential to be useful (and fucking up Osborn's plans would be fun).
Then again, Bendis never was one to pay attention to anything other writers were doing, so we'll see.
