So there are some logistical hurdles that must be cleared for this matchup to take place, but there is hope to cling to. Sony is apparently keen on more integration of its Spider-verse films and the Avengers, so perhaps there is an opening for the Kingpin to make his way into the film universe if all the requisite parties can come to an agreement. Vincent D'Onofrio wants it, so that's at least one less step necessary to make this a reality. And hey, we never thought Sony would allow Spidey in the MCU or the X-Men would be returning home, so stranger things have happened.
