To be honest, I think the only villain I'd like redone is Doc Ock. I support Norman Osborn as a bad guy, but I've had enough of Goblin, Green, Hob, or otherwise. I love the Green Goblin and all, but he doesn't need to come back. We've seen the Goblin 3 times, and we don't need another Joker situation where every piece of Batman media is about the Joker and no one else. Yeah, he's his arch enemy, fine, but that doesn't mean we need him in everything, and Spidey has so many other great villains that it'd be a shame to use the Goblin again. Besides, arch enemies don't mean much when cinematic supervillains disappear after one movie. And no, I don't want multiple movies of Green Goblin either.
Doc Ock is pretty much just as iconic of a Spidey villain as Goblin, and plenty have argued he's Spidey's real arch enemy over GG. And it's been 12 years since Spider-Man 2, so he's definitely due for another cinematic makeover. And that's only if they decide they gotta reuse a villain, which I honestly don't think they need to do.
