Alternately, they introduce his Earth in COIE and you find out that it's a Marvel Earth, and most of its superheroes and inhabitants are killed during the Crisis except for all the Spider-Man related characters.
After COIE then he'd be seen in Legends and probably get his origin modified. I don't know if they'd put him on the JLI, though.
