How does this sound? Take the winners of the four BCS bowls, Rose, Fiesta, Sugar, and Orange. Based on their ranking entering those games you have #4 play #1 and #2 play #3 all at neutral fair weather sites or domed stadiums. The winners of those two games play for the championship on the off Sunday before the Super Bowl. The integrity of the regular season and conferences remain intact as does the bowls.
As an example of embracing the "new and improved" (and certainly not the stuff of tradition), college football overtime's system was pure genius. Initially I was skeptical of the plan, but seeing it in played out in action over the past several years (like that thrilling UDub game this past weekend) has made me a believer and a fervid advocate.
