using Bonanno as case in point, I think all of Vito's sons are base don Bill, Sonny hot tempered, extra martial affair, Bill had both, Michael, college kid kind of out of his element, Bill was in college when he was made, like Fredo some thought he was a little stupid/eccentric (Mary Ferrel Wiretaps)and like Tom he was made to be consigilieri.

The difference between that and real life is that, Vito only had 2 capos, and Bonanno had much more all who did not agree, and some who were tied into other bosses (Gaspar D and Magaddinno) however even Tessio hooks up with Barzini...
