I think it needs to be more than 4 or 6 groups ... the truth is, there is going to be a top dog that rises to the top of each grouping. That is exactly what has happened with the re-aligned conferences. Bama has jumped to top dog out of 14 teams in SEC, Clemson is top dog out of 14 teams in ACC, OSU top dog in 14 team Big 10, Oklahoma is top dog in 10 team Big 12. Part of the reason why Pac12 is "down" is because they do not have a dominant team right now. I would rather see there be 16 conferences in FBS, with only say 8 teams max per conference. Then you at least have 16 top dogs. I also think teams like Cincinnati, or UCF from a few years ago, need to be given a shot. If they run the table, then they should get in over a 1 loss Clemson team, or an OSU team that only plays 7 or 8 games. As we saw with Boise State playing in big bowls years ago, these teams can sometimes compete with the bigger conferences at least for one game. So why not give them a chance? It would make things more interesting. Smaller conferences also give you a chance to play more non-conference games, which can be used to restore many traditional rivalries. Unfortunately, it will never happen because of the money.
