Don't see any realistic way that ever happens. Create a superleague filled with 20-24 of only the most elite programs and before long, that superleague will have a top half and a bottom half. All of a sudden, half of those elite programs/brands are no longer viewed as "elite" because they're finishing at or below .500 every year. And then what's to stop the top half from thinking "why are we subsidizing these 10-12 programs that aren't on our level?" and deciding to cut the fat. Then you have a 10-12 team super-superleague filled with only the most elite of the elite brands. Before long, that super-superleague will have a top half and a bottom half. All of a sudden, half of those elite of the elite programs are no longer viewed as the elite of the elite because they're finishing at or below .500 every year. And then what's to stop the top half from thinking "why are we subsidizing these 5-6 programs that aren't on our level?" and deciding to cut the fat.... etc., etc., until you're left with Bama, tOSU, and Georgia dancing in a very small circle.
Don't see it happening.
