Travel expenses in the for USC and UCLA will be hell. Your new PiG10 West will be USC, UCLA, Nebraska, Wisconsin, Iowa, Minnesota, Illinois and Northwestern - still nobody that can beat Ohio State.
You might want to put Michigan in there.
The concluding line of the fight song is “The Champions of the West.” (Before it was the Big 10 it was the Western Conference. Michigan State with a slightly different name made it the Big 10).
For $100 million yearly the colleges will be able to manage their travel budgets just fine.
