I would have Peter Parker be in the MCU first. He would be the theatrical Spider-Man. Race optional. Could be black, hispanic, asian, white, etc. He would be in the Captain America: Civil War film.
Then there would be an easter egg in Spidey’s film. at some point, we would see a young man who witnesses Spider-Man in action and is in awe. The aware viewer would see this kid and know… Miles Morales.
Then, I would announce a Spider-Man series with Netflix. This series would feature Miles Morale, initially in New York, where he gets bit by a radioactive spider. Frustrated by all the dangers in New York, such as alien invasions and psychotic robots, his parents decide to uproot him and move to another large city. Say Chicago or even Los Angeles. In this new city, Miles is inspired to use his developing powers to become Spider-Man of (New Hometown).
There you go. You get Peter Parker and Miles Morales at the same time.
