Ironic that Independence and Liberty mark some of the more lowly bowls.
Back on your prior comments, my opinion (since you asked, of course), is that the bowls and playoffs be merged. The early, lower-ranked bowls are fun because they're insignificant. The other bowls are great because they're meaningful.
A 12-team playoff to the seeded teams (throw in conference champions, etc) would be great, but we still need the lesser bowls. You could even have a two-tier playoff system with 12 top teams vying for the championship and 16 lesser teams (give every conference at least one berth), and the winner of the second tier playoff gets a guaranteed spot in next year's top playoff.
There is some element of fun to the bowls, and while they're terribly inefficient at producing champions, they won't go away (because of money) and shouldn't go away (because they can be useful)*.
*Some of them should go away, but not all of them.
