As far as the playoff/+1 scenarios go, here is what I would love to see.

6 teams, all major conference champions, the top 2 BCS rankings get a "bye"

This year would look like this.

Clemson/WVU - Orange bowl
Oregon/Wisconsin - Rose Bowl

Clemson/WVU winner/LSU - Sugar Bowl
Oregon/Wisconsin winner/Ok. State - Fiesta Bowl

The 2 winners would meet in New Orleans for the title(championship locations would rotate like they do currently)

IMO this is a great option. It eliminates all the arguing over all the At-Large crap. If you don't win your conference or don't play in a major conference, you don't qualify. It also would allow the bowls to keep there conference tie-in's for the most part. The only difference is the first round of games would probably have to be played before Christmas or the season would need to be extended by a week.
