I have thought of this but didn't think others would. I still haven't formulated my thoughts on it completely. East and west would play each other more, but East v. East and West v. West, wouldn't. I would guess amongst the east that the traditionalists would like playing the "real" Big Ten teams more often.
So far I am satisfied with what we have, but as I am a blossoming oldster, I miss playing Ohio State, Michigan, Indiana and MSU most years, even though at 5'8" I wasn't actually the guy playing them.
