Let's say that upon the death of Neil Dellacroce in 1985, Paul Castellano appointed John Gotti and Tommy Gambino as dual Underbosses, instead of Tommy Bilotti. And let's say that part of that deal would be that Tommy would become Acting Boss with Gotti as Underboss if Paul was sent away to prison in the Commission trial.

Would John have accepted such a deal, being a dual Underboss with Tommy, and then being Tommy's Underboss on the event that Paul went to the can?

Or say Paul named Frank DeCicco the new Underboss when Neil died, would Gotti have accepted that?
