They already have only 11 teams since UConn went indy, so if they lose three they could still do a championship game. If they lose more, having a championship with only six or seven teams might be a tough sell (they have to have at least six teams to still be a conference). Plus depending on who they might lose, the networks would probably want to renegotiate their TV deal.

Doubt that Army would come in to the AAC. They want the game with Navy to be the last regular season game of the year for all of 1A/FBS football, even after conference championship games. That can't happen if they're in the same conference and it has a championship game; their game might affect who plays for the conference championship. If they need to add teams, look for them to raid some of the more successful teams from other G5 leagues.

I seriously doubt Wichita State would try to revive its football program. They do not have any type of football program and old Cessna Stadium would take some serious $$$ to bring it back as a modern football stadium. As a matter of fact, the Kansas Board of Regents approved the demolition of the stadium in April, 2020, although it is still standing. The Koch family has heavily invested in Wichita State over the years and Charles Koch Arena (WSU basketball) is fantastic, but I do not think Wichita State would throw serious money at starting a football program from scratch. They spend serious $$$ on all of their other sports, especially the basketball programs.
