Instead of two divisions, you could have three:

CA: Stanford, Cal, USC, UCLA
NW: Oregon, OSU, Washington, WSU
Mountain: Arizona, ASU, Colorado, Utah

Each team plays the three others in their division, a home/away from each other division plus one "bonus" game.  The top two division winners play each other in the conference championship.

FWIW, when Utah/Colorado joined, part of the deal was that they would be able to play USC/UCLA every year which is why they are in the south. Not sure if that's still in play with any future moves.
