Genovese, Casso would still be the same guy. He'd just be under Chin Gigante, if history were to turn out the same aside from his family affiliation.

A funny Casso story comes from the Five Families book. Gotti and Gravano are going to a Commission meeting with Amuso & Casso and the Chin. Knowing the heat between Chin & Gotti, they're in an underground garage. Casso looks around with this smirk on his face while they're going up to this meeting and Casso says "This would be a good place to do a hit". According to Gravano, he and Gotti almost shit themselves. It was the same meeting where Gotti bragged about making Junior and Chin says "sorry to hear that".
