Hey for your Spider-man story, you should have Spidey call Nightcrawler to help teach supergirl by having him follow her around and make sure she doesn't do anything stupid in the #fightatthemuseum chapter, honest everyone overlooks some of these things, he's friends with multiple X-men and is best friends with the human torch. Maybe as a Spider-man writer take more aspects besides the whole sinister six thing, and branch out into other aspects of Spider-man, like the time he had stingers and later on lost them, or his clones, Ben and Kaine? I'm just saying take some stuff from comics, it'll have a very fresh feeling compared to a lot of fan fiction on here
