I'd be fine with miles morales. It makes no difference who wears the mask as long as the story is good. Guardians showed that if handled right nobody would care if a lesser known character is the lead in the movie as long as it's a good movie.
Speaking of...does Sony on the rights to "Peter Parker:Spider-Man" or just the name "Spider-Man"? Because after the last 2 movies I'd have preferred marvel just say "fuck you and your shitty ass movies" to Sony and bring in Miles to their roster and call him Spider-Boy. They don't need Peter Parker to make a good Spider-Man movie.
