Right now, I think anything....ANYTHING, like crossovers/appearances etc between the movies and t.v, from Fisk coming from an adult netflix show to a family spider-man movie to the Agents and Defenders showing up in IW, is possible. It just is. Anything can happen.
But Marvel have to want it, truly want it, to make it happen.
Fisk in Spider-Man? Easy.
He's the Kingpin, he needs no introduction other than controlling most of the organised crime in the city. Turning peoples heads to mush, doesn't have to happen. He can be calm and collected like he was in S1, with some viciousnous behind closed doors. And he knows he can't take Spidey in a fight, he's superhuman. And Spider-Man, just like DD did/does, interfers and ruins plans, costs him money and assets and in general, pisses him off.
Kingpin can be responsible, like in the Ultimate comics, for the creation of another supervillian, like Scorpion, Rhino, Sandman, Shocker, Vulture...any and more. That supervillian causes problems for Spidey in most of the movie and the final fight between them can cause major damage to Spidey who barely wins. Then Kingpin comes in, Spidey is weaker as well as pulling his punches but Kingpin is just going at him, enraged at this pest. And Spidey wins.
The hardest part would be fitting it into DD and the timeline, and while I'd like him to show up, he doesn't have to. But it's possible. So very possible.
