Crime Syndicate Cinematic Universe

Maximus Rex

Since movie franchises seem to be all of the rage right now in movies, somebody needs to do a Crime Syndicate/Mafia cinematic universe detailing the lives of some of America's notorious gangsters. The ? would be kinda like Broadwalk Empire, but would detail the rise of cats like Joe Masseria, Salvatore Maranzano, then formation of the Commission with Luciano, which would tie into Carlo Gambino, Vito Genovese, and how they conspired against Frank Costello, among other stories that could be told.The thing is how would you keep this ? from becoming repetitive and keep the stories interesting.
