Assuming Nebraska-Omaha's attempts to join the MIAA are successful, I would be surprised if this "logical" move didn't take place:

Nebraska-Kearney to the MIAA

This would create a western division of UNK, UNO, Fort Hays State, Pittsburg State, Emporia State, and Washburn, all of which are in Nebraska and Kansas. The eastern division would consist of all Missouri schools: Missouri Southern State, Missouri Western State, Northwest Missouri State, Southwest Baptist, Truman State, and Central Missouri. The MIAA would have 12 and the RMAC 13.

Hays, KS is actually slightly further west than Kearney, NE, but UNK is in the 14-team RMAC instead of the currently 10-team MIAA.

Chadron State, while also in Nebraska, is only five to six hours from the majority of the RMAC. While Western New Mexico is farther from Chadron than the entire MIAA, most of the MIAA would be 12 to 13 hours away.

UNO (NOT University of New Orleans, but rather University of Nebraska - Omaha) HAS been admitted into the MIAA.

So of the 5 North Central Conference schools left in the lurch when North Dakota U and South Dakota U went to D-1, 4 (Augustana, MSU-Mankato, UMDuluth, and St. Cloud St.) landed in the Northern Sun, and UNO in the MIAA, and that cleaned up all the refugees from the NCC (which is disbanding).

The MIAA is at 11 with that addition of UNO.

The RMAC is at 14, with 2 schools in New Mexico, 10 in Colorado, and Chadron State and UNKearney in Nebraska. So, yes, the eastern-most Nebraska school of that pair (UNK) might be in play soon.

UNK would be a rather nice fit in the MIAA. Take CSC and bring back Missouri S&T as well and you got a 14 member MIAA.

Chadron is much more comfortable in the RMAC footprint than the MIAA. It's about 4 hours to Denver from Chadron, compared to the closest school in the MIAA (Fort Hays), which is 7 hours. Fort Hays and UNK are kind of in no-man's land, as they're both right in between what would be the western MIAA boundary (eastern KS/NE) and the RMAC (the KS-CO border), so they could go either way. Chadron is in the northwestern corner of NE, and has a much more direct route to get to Denver and most of the RMAC schools (US 385 straight to I-76) than to Fort Hays (US 385 to I-80 to US 183), let alone getting to the Missouri schools.
