How about Alien meets Clemenza. An alien bursts out of Clemenza's belly and goes on a rampage whacking wiseguys right and left. They talk the alien into marrying Connie and, in the meantime, resurrect Sonny who, mistaking him for a resurrected Carlo, beats the crap out of the alien. Wanting revenge, the alien meets up with Roth, moves to Cuba, but gets into drugs and alcohol, and ends up as a featured act in one of those out of the way Cuban nightspots.

I think it has possibilities.
