I say keep the big 4, rose, orange, sugar, fiesta. Rotate them so that they host semi final games every other year. The two that aren’t can be quarter final hosts that year. The rest of the previous games are at the higher seeded teams home field. Quarterfinal games are the two mentioned above and Cotton and Cap One.
Only if the Rose stops expecting to always have their 5pm Eastern kickoff no matter if they’re in the CFP or not.
