Great analysis, I actually asked you something similar in my drug thread, if you subscribe to the theory of liberal and conservative factions on the commission, and on lucky you are right on the money.
Costello was always kinda aloof it seems, like he was more concerned with money and politics and fitting in with high society.
I actually think genovese coulda have been a good boss, the moves he pulled in Italy were, like, fuck....
But he was too gangster, allergic to taking orders I think, I have a cousin who had that mentality, just was not built to be a soldier.
