If San Jose State leaves, I wonder if Michigan would leave the CWPA and make the MPSF an all Big 10/Pac 12 conference:

Indiana
Michigan
Arizona State
California
UCLA
Southern Cal
Stanford

At that point it might be easier to have it run by the Pac 12. The Mountain West or WCC could take over the GCC:

Fresno State
Loyola Marymount
Pacifc
San Diego State
San Jose State
Santa Clara

The MW/WCC hopefully would pick up at least Cal Baptist as an affiliate since the Lancers are moving to Division I. Azusa Pacific and Concordia Irvine could then join the WWPA, which is composed entirely of Division II members.

The CWPA and MAAC would then have the remaining eastern Division I members:

CWPA - Brown, Bucknell, George Washington, Harvard, Princeton, Saint Francis (PA)
MAAC - Iona, La Salle, Marist, Siena, Saint Francis Brooklyn, Villanova, VMI, Wagner
