Knowing Toto' Riina's mentality, he and the other Sicilian bosses would probably try to kill the American bosses you listed, because they are too charismatic and wouldn't obey him.
Who would have won?
Thats a tough one man. Those sicilians love bombing, so our guys in the states would pretty much have to walk everywhere to be safe lol. On the other hand, the American guys had more cash, more power (dare I say because sicily is the size of what, Massachusetts?) I think if Chicago teamed up with any of the "big three" in NY (genovese, gambino, lucchese) they could wipe sicily off the map. And I mean Palermo, Corleone, etc.)
