A lot of major schools, not in the big 5 may not go with the idea. With only 3 at large spots open, that could be ate up pretty quickly with conferences that are mid range, leaving independents out of the mix. Or, vice versa, independents in, and conference winners out.
My question is this. How many total schools are in the program, and how many of them are in the big 5? I don't know off hand, but if they don't total half of the schools, they might have a rough time getting confirmation at 8.
Just shooting from the hip here. Not certain it will be an issue.
