I don't have a problem with these regions but I think BU would. They are still Pairwise #2, so should get the AHA champ. But with only 2 #4 seeds to work with there's no easy solution. Lots of rabbit holes indeed, and I don't see much movement in the 4 Pairwise range. St. Cloud and WMU could switch spots but that doesn't resolve anything. An upset in one of the conference tournaments could make the first round matchups much easier to figure out.
