Not difficult to solve.
Top 12 teams are in mix. Top 8 make CFP.
MAX 64 post-season teams. Teams 13-64 play in bowls between 12/15-12/28. NO bowls after this date.
Use NY6 bowls plus a few of the upper-echelon bowls of tradition-past.
12/24: Two playoff games (utilizing NY6/upper-echelon mix) NO other games allowed!
12/25: Two playoff games, same conditions as above.
12/31: Two bowl games featuring teams 9-12. No other games allowed, giving these 4 some "spotlight cred".
1/1: Two semifinal games
7-10 days later: Championship game.
Non-P5 teams eligible provided: they feature a CCG OR they play 2 P5 teams (still need to earn ranking, of course). Notre Dame either joins a P5 conference OR they must have BOTH 2 wins over a P5 CCG winner or division champ AND have LESS than 2 losses. 2nd loss knocks them out unless/until they join a p5 conference.
Other: No games against FCS teams EXCEPT against a team from same state once every 3 years. Play UNI this year, fine. Play them again before the 3rd year, NOT eligible for CFP.
In conferences with 10 teams or more, MUST play 9-game schedule. Must have CCG.
In 9-game conference schedule, non-conference games must include one P5.
