I'm surprised that nobody tried a retro team up like that Batman/Captain America team-up that was done in the 1990s by John Byrne.

I wonder what it would have looked like if the Ditko era high school Spider-Man were teamed up with the 1960s era Teen Titans. (circa 1982 with the updated team, Peter would have been kinda 21-22-ish, in grad school, so not a teen anymore). The Titans were not allowed on the Justice League, and Spider-Man was not an Avenger yet.
