Since I'm an entrepreneur with my company pretty much on auto pilot right now, I'm able to waste my time thinking about this stuff (business side of college football has interested me for a while).
Anyway, this is my solution to the 16th team question, operating under the assumption that Notre Dame joins as a full member (so this is year 2015 and beyond).
Basically, the ACC reaches out to Penn State and Texas to add both full athletic programs along with Notre Dame. That puts the ACC at 17 full programs. However, Duke turns its football program into a hybrid independent/ACC like Notre Dame is doing starting in 2014. Since Duke will never realistically be able to compete in the new ACC, Duke goes hybrid, scheduling 4 rotating games (out of conference) with ACC programs every year, for an 8 year home and home with all 16 football programs. Then Duke schedules a mixture of Vanderbilt, Kentucky, Illinois, Indiana, Northwestern, North Carolina, Kansas, Baylor, Arizona, UCONN, Lousivlle, Cincinnati, Navy, Army, Airforce, as well as a Stanford or UCLA here or there and some D-IAA teams. Basically, that's at least 8 games that will be on the ACC family of networks, and probably 10-11 every year. I actually think this would improve the Duke brand with Duke keeping a full TV revenue share (Duke bball is disproportionate in its value). It would become more like Navy (an average but national program with national following).
This frees up the ACC to go to a 16-team pod format in football with probably Texas and Notre Dame in the same pod with Pitt and BC; Maryland, UVa, VT and PSU in the same pod; UNC, Syracuse, NC State and Wake Forest in the same pod; and GT, Clemson, FSU and Miami in the same pod. Texas would probably keep its game with Oklahoma and Notre Dame its game with Southern Cal. That would definitely make for some nice programming for our ACC TV partners.
I can't even imagine the money payout for this.
