One of the many ideas bandied around online is to simply incorporate The Amazing Spider-Man franchise into the MCU - overtures towards this direction have been made before, with the Oscorp tower nearly making its way into The Avengers' New York skyline - but the two worlds are simply incompatible. The Chitauri invasion in The Avengers wreaked havoc across New York, and throughout Phase Two of Marvels movies the characters have been shown to be angered, saddened and repulsed by the events. Seeing as Spider-Man is set in New York, yet no nods towards this groundbreaking event were made, it would be hard to integrate the movie into the wider network. The Amazing Spider-Man franchise has been grounded in science, so fitting Marvels upcoming cosmic and mystic heroes in with Garfields iteration of the character would be virtually impossible. It isnt Garfields fault that the franchise is incompatible, but it would be complicated and convoluted to bring the star into the MCU. It makes much more sense to start anew with a fresh face.
