I really like that idea Enzo, the only thing they would have to do would be to find a whole new family for the flashbacks. They could have De Niro still be Vito but they would need at least 4 young talented actors to be young Michael, Sonny, Fredo, and Connie.

The other tough part would be convinvcing Pacino, De Niro, and Shire to all come back one more time. I know Andy Garcia has expressed interest in a fourth Godfather but he cant do it all alone.
