Perhaps in this pair’s quest of multiversal multitudes, not only would Peter Parker’s existence come into play, but also the entire Spider-Verse.
This would lay down groundwork for potential cross overs with Venom, Morbius, and even the entire Spider Fam from Spider-Man: Into The Spider-Verse.
The cherry on the sundae would be that if Sony can cast a candidate pretty damned quick, they could even use this film to tease the eventual arrival of the newly announced Madame Web, formally introducing Cassandra Webb and Peter Parker.
