At this point, I think it would be incredible TV to take the standings and reseed the teams to create 4 different 4 team brackets. If you are in first place in your pod, you get placed in a bracket with all the other 1 seeds to duke it out in a playoff for the Big 12 championship. All the 2 seeds get placed in a bracket together. All the 3 seeds get placed in a bracket together. All the 4 seeds get placed in a bracket together.
Winner of semi #1 plays winner of semi #2. Loser of semi #1 plays loser of semi #2 in each bracket. If you want competitive games and people tuning in to games that matter in November, literally make the conference title into a regular season playoffs and then put teams of a similar level against each other so we have good games. Because every team is guaranteed 2 games in their bracket, you still play 9 conference games and can play 3 non-con (if those even really exist in the future). For all I care, we can try to find a way to even play a 13th game somehow. I haven't thought that far but lets get innovative and create a cool product doing it.
