Let all 4 remaining major conferences schedule however they like to determine a championship within some max game constraint (13-14 games?), SEC Champ and ACC Champ play in annual rotation between Sugar Bowl and Orange Bowl, Pac1X champ and B1G champ play in Rose Bowl.

BUT, I would have that winner play one more game for a national championship.

I think the conferences would end up being the playoff with new setups that allowed for 2-3 rounds of playoffs to determine the conference champ which would allow for more creativity in organizing/scheduling these new massive leagues as well as more incentive to just go out and play the hardest/most intriguing OOC games. Hell, bowls could transition from post season to conference playoff/championship hosts. A lot of possibilitites that we'll never experience.
