The problem is the 14 are not homogenous in their aims. Burnley, Brighton, Crystal Palace and the like need the renegade six to keep the PL TV value inflated. None are serious about ever competing in top level European competition. Everton, Aston Villa, Leicester, and West Ham would have very different ambitions. Leeds and Wolves would prize consolidation and then progress. They will not present a united front.
I expect a compromise to eventually emerge. Bayern Munich will be the bridge to this as Karl-Heinz Rummenigge straddles UEFA, the ECA, and the renegades. Bayern would have to be in a super league for obvious reasons, but cannot be due to the power German fans wield over their clubs. He is, by default, the one who sees both sides of the story. I can't see the renegades being ejected in the end. Points could well be docked, but turkeys will not vote for Christmas.
