I think that the playoff should change to just a BCS+1. Basically, all the bowls are populated like they were before BCS even existed. Then. after the bowls, the teams ranked 1 and 2 in the BCS rankings play for the championship. And the BCS rankings are not released at all until after the bowls. This flat solves the "other bowls don't matter" problem and means that the bowls are the playoff in a lot of senses.
