I like 12 team conferences. 2 6-team divisions with a championship game in football and 22 game round robin schedule in basketball.

I peeled off NCST and Wake from the ACC. Vandy and Miss St. from the SEC. MD and Rutgers from the B1G and added most of them to the AAC. A few members of the AAC got downgraded but I didn't go any lower than the MWC in this model.
