I liked the idea where you borrow from the pro soccer model and you have the MAC combine with the B1G and every year the MAC champion moves up to the B1G and the worst team in the B1G moves down to the MAC. That way there's the potential for movement every year and theoretically the B1G would improve because its constantly eliminating its worst team. It also makes every game more meaningful as bottom teams now have a reason to compete at the end of the season.
I forget where I saw it at but the author had estimated Indiana and Minn would basically become permanent MAC teams.
Won't ever happen due to money and politics, but I assume this wouldn't be for all sports, only football?
Football only. The idea is a double edged sword. Yes, every team in the MAC would have a shot to get to a national title game (theoretically.) But we'd just be servants to the Big Tendozen. Where would our pride be in our conference if we (excuse the term I'm about to use) whored ourselves to the Big Ten?
The solution is to somehow get FBS football to the point where all teams have a shot at the national title like in FCS. We would be a part of the problem, nothing more.
