Before I offer the crazy question, I want to say that I can't wait for the Sioux to become an official member of the Big Sky and I'm just tossing this out there to get kicked around.
What if .... The Sioux went FBS? The WAC is begging for schools to join.
One of the reasons that has been given for allowing the Sioux to forgo the nickname and logo, is that that UND wouldn't be able to host any NCAA playoffs games. The only teams that I can think of that could host NCAA playoff games are the football team and possibly the women's hockey team. If the Sioux went the FBS route, their is no playoffs. You are playing football for conference championships and bowl appearances.
Sure the Sioux wouldn't be able to play Minnesota or Iowa, but I'm sure there are a large number of teams that would play the Sioux.
UND could tell the NCAA, put us back on your "hostile and abusive" list, we are keeping the name.
