An "association" of independents of the biggest brands would be sick.
ND, Michigan (they were pretty unhappy with the idea of the B1G private equity deal), FSU, Clemson & Miami would be a good starting point.
You would need 2-3 more to be able to get enough games that you could then fill-in the schedule with teams that remain in the power conferences and to make it so that it allows for a national schedule.
So....
West Coast Pod:
Midwest Pod
Deep South Pod
Florida Pod
That gives everyone 7 games. Their rivalry games (ND v. Navy, Michigan v. Ohio St., etc.) gets everyone to 8 games. 4 games left to schedule other marque games. Or, find 1-2 more schools to join so it's only 2-3 remaining games that need to be filled-in.
