Respectfully, none of this will do what you want it to do. Winning is creating the disparity. We shouldn't punish teams for success, but we should make the next year's schedule very difficult for them. For example, the first place team of the Big Ten should have to play the first place team of two-three of the other P5 conference the following season. Nine to ten conference games....no cupcakes for anyone. Go back to a computer deciding two teams that make the championship game, no "playoff". Just football with a meaningful season start to finish.
If Ohio State, next year, can beat Clemson, Oklahoma and Alabama in early season play then run the Big Ten, they deserve to be in the championship. If not, someone else gets in. Same for the other three.
