Not necessarily superconferences but...

Notre Dame goes a little further into ACC football by agreeing to join a division and play only 7 ACC games. Notre Dame may schedule the other ACC teams in OOC games. The divisions are realigned. In turn, the ACC gives Notre Dame full access to the ACC championship game based upon conference game win percentage. The ACC finalizes up to 16.

The Oklahoma schools jump to the SEC. Texas heads west because Texas' ego gets in the way and the PAC is willing to let Texas maintain the LHN. The B1G does nothing. The XII expands from the AAC. The AAC disbands as the remnant merges with some MWC schools.
