I'm not the only one thinking of this scenario.
SI: "Could Stanford be on its way back to the Pac-12?"
"Rejoining the Pac would make sense for a multitude of reasons. First, both the schools would return to playing games in their geographic regions, once again playing games exclusively on the West Coast. This season, Stanford is slated to play teams like Syracuse, Clemson and Notre Dame on the road, making the travel schedule a very challenging one for them. Also, having college athletes, who have classes to worry about, travel to games across the country many times throughout the season could cause issues in terms of staying on top of their schoolwork. For prestigious academic institutions like Cal and Stanford, that could create some problems both on and off the field."
There has been a lot of chatter over how Stanford will handle being in the ACC, which comes with a lot of extra travel baked into their schedules across sports.

Stanford/Cal could win a lawsuit to get out of the contractual stuff, or most of it, if the ACC started changing in a big way. Fraud on ACC's part.
