There is zero chance of that.
1) No current MWC or PAC school is going to support the idea they could be demoted to cusa level and earn even less.
2) No Northwest team is going to want to travel to the far Southeast to play conference games.
3) You are misrepresenting what was in the original proposal. If it went to 24 teams, they would invite REGIONAL teams from the Central, Mountain and Pacific timezones. That could include inviting some "regional teams from the AAC, Conference USA or WAC" according to the proposal. They were talking about a couple schools like UTEP and NMSU along with Tulane, UNT, UTSA from AAC potentially, not FIU and KSU, or the entire conference.
