The transitive property thing you are implying here doesn't work because Ganke is a character from
Miles' world, not Peter's. You can believe that Miles is a bland version of Peter and that he's "stealing" characterization, but I'm sure a number of fans can argue with that. The Ganke thing can't be argued. That character in the movie is Ganke in everything but name. It's clear they took aspects of both Spider-Men and linked them into Peter.
Anywho, just found there are rumors that Miles is in the film and has already been cast. Popular theory is that he'll be portrayed by this young man.

Thinking about it, I'll forgive this Ganke transgression if they do one thing. Make Miles best friends with Kamala.
