Montana and Montana State would want to be like minded schools in the Mountain West.
Montana is an R2
Montana State moved to an R1 school. They both fit the MWC profile except for San Jose State and Fresno State.

UTEP would take a Mountain side spot instead of New Mexico State.

UC-Davis and Portland State are both R1 and R2 which they do fit MWC.

MWC could grab to be the first 24 team conference. 4 pods of 6. This could get Hawaii in for all sports with 5 California schools.
Portland State and Eastern Washington would join Boise State, UNR, Utah State and bring BYU back for all sports.
Mountain will get Montana and Montana State.
East would get UTEP, UTSA, Missouri State, Northern Iowa, NDSU and South Dakota State.

This would boast the football and basketball. AAC and MWC do have a much better path of getting into the playoffs than C-USA, MAC and SBC. The schools in the other 3 conferences need to build onto their strength to try and get into those 2 conferences. UMass., Southern Miss. and ODU have been mentioned in joining the AAC. With the plight of UConn.? AAC might have to expand with UMass. and maybe a Northern Illinois to help UConn out. Illinois State could be picked to join the MAC to replace Northern Illinois.
