[/quote]I wonder if the ACC would retain power conference status here. They do consist of teams which had all been in BCS AQ conferences (some perhaps undeservedly). Their case is weak though.[/quote]

I wondered the same thing. Power status, at least with respect to the BCS/CFP, comes from having one of the participating NY6 bowls committing to having a conference be the designated host every year that they aren't part of the championship rotation.

I think it would have been possible that the Orange Bowl might make (retain) that commitment to the ACC. Maybe more so if they chose to make UCF their 12th team instead of Temple (giving them 3 of the 5 top FBS schools in Florida).

I don't think either the NCAA or the other four power conferences would have had a problem including these schools in the group that is granted autonomy within FBS.

I'm not sure if the remaining four conferences would get a guaranteed spot in a future CFP in this scenario.
