Let me be clear, I don’t want much Miles (if any) before they are essentially closing the book on Peter. It would be disrespectful to both characters, but especially disrespectful to Miles Morales who means a lot to a lot of people and is quite popular in his own right to just force him into a Peter Parker Spider-Man movie instead of giving him his own movie.
It would seemingly compromise both characters in a movie, although Insomniac pulled it off in the 2018 video game pretty well and then gave Miles his own origin game shortly after, but that’s a different medium.
