Just take SDSU, Boise St., and Fresno St. from the MWC, and SMU from the AAC.
That's fairly regional and gets you to the magic number 8.
If you want to go to 10 then you can consider adding Memphis and Tulane from the AAC as well.
Beyond 10 there's no real good options. Maybe Hawaii and Utah State from the MWC but that's pretty underwhelming.
It's obviously not the ideal conference but it's not as bad as you think. Basketball would still be very strong also.
That’s not feasible because the MWC has a $34M exit fee. It cuts in half to $17M if they wait a year but even that is a steep price to pay to jump on a conferences boat that has almost already sunk. With NCAA two year grace period they could add a few from AAC for next year to get to six or seven and then wait a couple of years with the grace period to see what the situation looks like with the MWC.
