I could only see this film working if they do a back and forth thing like they did with Part II, kinda comparing Vincent to Sonny, or something along those lines. Maybe Mike would be Vincent's consigliere. The reason I say this is for the simple reason that I cannot imagine a Godfather film without Al Pacino. Michael would no longer be the Don, but he could still play a major role in the film.
