The ACC is never going to put FSU, Miami, Clemson all in the same division. Never. From a big picture perspective (certain recent history notwithstanding), these are the 3 most attractive football programs in the entire conference. Plus, only the teams in the south are guaranteed to get trips to Florida, while the north is shut out, except when they get their 1 non-crossover game against the other league.
Not to mention that UVA and VT will scream to whoever will listen about not wanting to be in the north division and having Wake Forest as their only division mate in the bordering state of North Carolina.
I don't know the bylaws for division re-org, and if it's a vote, and how many votes are needed. But I think there will be enough opposed to make this a non starter.
Now, get ND to join full time, put them in the north, at least you give people something to think about. And then please don't balance them out with UConn. It would be the broccoli next to the Filet Mignon. At least find some mashed potatoes, somewhere, anywhere.
