Spitballing how this shakes out:
USC, UCLA, Cal, Stanford, Oregon, Washington to the Big Ten
Colorado, Utah, Arizona, Arizona State to the Big 12
Oregon State, Washington State are left without a chair and probably have to go Mountain West.
This is ultimately going to set up as two 20+ megaconferences being the SEC and the Big Ten.
Once the Big Ten gobbles up the western schools, both conferences' next target will be UNC and then we'll go from there where they pluck the rest of the ACC desirables.
