616 peter and 616 MJ die saving the world from the Maker and Ultimate Peter/MJ come over to 616 to replace them. That's how I'd fix this mess. Like what happened with Miles except not gay and retarded.

Also somebody throws evil ben reilly/jackal/chasm into a fucking volcano holy shit keep that faggot AWAYYYY from Peter. If you want a young 20-something unlucky fuckup Peter, well now Kaine is still around and there's no longer any mistaken identity issues since he's a decade younger than Ultimate Peter. Bring back Scarlet Spider and Araceley and now you have Peter as married family man with a wife and kids, Miles for the EXAGGERATED SWAGGER OF A BLACK TEEN, and Kaine for 20-something parker luck.
