There are a few guidelines that I feel need to be followed for a Godfather Part IV to be made. First of all, Pacino can't be the main character. We already saw his death, so in my opinion the only role Pacino would be able to play would be an off-and-on advisor for Vincenzo Corleone, if the movie were to take place in the late '80s to early '90s. Secondly, if the movie were to take place in that timeframe, every character still alive must be played the same actor/actress. I can't stress that enough. And if it were to take place in the '30s, then a reasonable facsimile of the previous actor must be used for each character. Thirdly, the storyline must tie in to the other movies. I'll wait for comments.
