What if the ACC expanded to 20 schools and merged with the old Big East like they probably should have done in the first place, the conference could truly become the first super basketball league.
Expanding with Rutgers and UConn would round out football at 16 and taking Georgetown, Villanova, and St John’s would finally allow the ACC to move to MSG and keep Greensboro at the same time as a tournament site.
ACC Basketball North: Notre Dame, Boston College, Syracuse, UConn, Rutgers, Pitt, Maryland, Georgetown, Villanova, St John’s
ACC Basketball South: North Carolina, Duke, Wake, NC State, Virginia, Virginia Tech, Clemson, Georgia Tech, Miami, Florida State
Double round robin basketball could be played with each 10 team division member and a couple made for cross over games for basketball. Both Divisions could have separate tournaments say one in MSG and the other in Greensboro. Each division champions could meet for the NCAA bid or request the NCAA to allow two automatic NCAA bids for the ACC.

There is only 1 non-football school in the country that adds any real value to any of the top 5 conferences, and that school, ND, is already in the ACC. If you're the ACC, you'd likely have more success adding Temple for all-sports than Villanova for basketball. Must remember, now that Temple is in the Big East with Villanova, that one advantage they had for recruiting is now gone. It might take a few years, but I expect Temple to regularly surpass Villanova in that one sport of value: basketball.
That said, the ACC is in the money making business. And at this point, at 14 football + ND for all other sports expect football (and hockey which the ACC does not sponsor), the ACC can't really do too much more to get better. If they wanted to dominate the northeast market, yes, you have Rutgers and Uconn which are a tier high above Villanova and Georgetown. So if they grew to 16, which is still pretty large, I'd think they'd have everything covered. At this point in the conversations about the Big 5 conference, other than ND, non-football schools start up the conversation about diminishing returns.
