Apparently, Paul's plan for succession included Tommy Bilotti, John Gotti, and Tommy Gambino serving as an equal trio of Acting Bosses, with Paul (hopefully) being allowed to remain as Boss even if jailed. If Paul wasn't clipped, he definitely would've went down with the Commission trial and spent the rest of his days in a cell. Now, this would've left Tommy Bilotti, John and Tommy Gambino in charge. I can't see John Gotti ever sharing power with Bilotti, but from what I've read, Tommy Gambino had a lot of respect and prestige...But John didn't seem the type to want to share power, so I imagine ultimately John and Tommy would've had to duke it out.

If they duked it out, could Tommy have won in a war against Gotti?

Would Tommy have made a good Boss--did he have the qualities necessary to make a good Boss?
