Pitting Spider-Man against a homegrown threat like Kingpin would be an excellent counterbalance to the large-scale, galactic threats that are coming in the Avengers: Infinity War storyline.
Because what Sony and Marvel are trying to do with Peter Parker in the MCU is keep his stories smaller in scale.
Maybe even with a Daredevil team up, bringing Charlie Cox over to the MCU (finally)!!
We know that Spider-Man: Homecoming is getting a sequel.
