I like what baseball used to do, skewing the playoff matchups to avoid rematches. i.e. in round two, Oregon would get the worst team remaining that isn't in the Big Ten. In this case, based on your presented percentages, that's Alabama. Texas would get the worst team remaining that isn't SEC (Notre Dame). BYU would get the worst team that isn't Big 12 (Penn St). SMU would take whoever is left (Ohio State).
That wouldn't entirely fix the problem, but I think it would help weed it out a little bit by making the one seed's path slightly easier, plus do some work to avoid rematches, which I don't think anybody wants to see playoff rematches. An alternate fix to this could be to give all five conference champions top five seeds, eliminating some of the ease of the first round matchup for what would now be sixth seeded Ohio State. At least that way whoever the G5 team is would get to play their game at home, potentially giving them a slightly higher chance to win.
That's why a bracket is kind of silly.
