What if Big Paul Castellano was never killed and John Gotti never ascended to become boss? Is anything different? Does the LCN face the same pit falls? Does it fall on the same hard times?

Especially, how do you think this would affect the Gambino family? And who would have succeeded Castellano had he died much later in life of natural causes? Does John Gotti still rise to the top? He was never sanctioned by the commission (IIRC)as the Gambino boss, it seems unlikely to me that given more time Gotti would not have been passed over for said title.

Further, if Castellano stays in power, does Gotti eventually get whacked? who takes over his crew? How does this change the face of the gambino family?
