You would go to a 3 year rotation/adjustment based on a point system. Based on the accrued amount of points over the 3 year span, top 4 or top 6 would get pushed up and bottom 6 would go down. If a program is tied for top then region finishes and playoff progression would be compared and for bottom then you could keep it simple. Bottom schools probably wouldn't mind going down.
I know of plenty scenarios where dropping down would've been best for a program and goin up would've leveled the playing field and even boosted the prestige of a program
