My thought was incorporating the NIT in some way as a play-in tourney. It would generate a ton of money, and it would make it relevant again, especially with some many bubble teams in years like this. My original thought was the winner of the NIT plays the winner of the NCAA, but the NIT gets treated like the losers' bracket of the College World Series and has to beat the NCAA champion twice, whereas the NCAA winner just has to win once.
Then a friend of mine, who is also a member on this board, suggested having the NIT Elite 8 being teams 61-68 instead, so that'd be your Dayton play-in games. I like both ideas. With the NIT elite 8 deal, conference tourneys and selection Sunday would have to change obviously.
