Trust me, I genuinely think you have great ideas; the only part where we're disagreeing is whether or not it could be the established in this series.
There's certainly a worldwide audience for Spider-Man. I have family in the Middle East, U.K., U.A.E, and Europe, and all of them have at least one person who is a Spidey fan. In fact, my family in Pakistan has Spidey posters on their walls. Japan is also another country where I can see a Spider-Man movie being filmed, as they too have a strong demand for him. There's a reason why the box office number for the international audience was around $700M.
But in regards to this series, what about May? What about Captain Stacy telling Peter, "This city needs you"? His death wasn't just significant for Peter and Gwen's relationship, but the fall of NYPD's leadership meant that Peter/Spider-Man is the new law (at least that's what I took from it). What about Peter returning at the end of TASM2 and establishing himself as NYC's hero? Also, Webb and company showing NYC without Spider-Man would absolutely mean squat if they went international in this series. But on the other hand, I guess you could look at it as foreshadowing if they went that route
This series has embedded a relationship between Spidey and the NYC too firmly already. If we go international for a reboot, I'll shut up and you can take my money.
