In my humble and mildly persuaded opinion, I think if the B12 were to expand, they need to pick the next best 6 and get to 16. Take the best options away from the ACC and even B1G and beat the ACC to a conference network. Put pressure on the ACC (it's really a race between the B12 and ACC for P4 survival) and if taking away the best eastern options from them forces an eventual collapse, the B12 can add a few schools (Louisville? Miami? NC State? Pitt for Backyard Brawl?) to get to 20 when it does.
Hypothetically, let's say that the B12 added for 2017:
UConn, Cincinnati, Temple, UCF, USF, and Memphis.
B12N angle: UConn brings northeast NYC and Hartford markets for B12N. Temple brings Philly. UCF and USF together are top 15 markets. Memphis brings FedEx dollars and good football/hoops combo. Cincinnati is not a terrible market.
Football: Memphis gives access to TN / Mid-Atlantic recruiting. UCF and USF double down gives twice as exposure into FL recruiting. PA and OH are added for football recruiting. UConn is the weakest add of the group but we more than make up for it elsewhere...all we have to do is remain competitive in football over the years.
Hoops: we obviously bring elite hoops that opens the door into MSG/NYC games. We give Kansas a game each and every year, not to mention bring the biggest name to year-round content. Temple and Cinci hoops are solid and good for fairly regular NCAAT appearances and success. UCF and USF are hot garbage but they are football recruiting and market additions. Memphis is a solid hoops add, even if Squid isn't cheating for them.
Academics: UConn tops the list at #57 followed by a slew of schools all in the 100s, but sport large enrollment numbers and would satisfy the football starved conference members.
Potential Division Alignment:
East - UConn, Cincinnati, Temple, WVU, USF, UCF, Memphis, Iowa State
West - Texas, OU, OSU, TT, KU, KSU, Baylor, TCU
All natural B12 rivalries preserved in the West. Conference Championship Game in JerryWorld every year. Conference hoops tourney rotates between Kansas City (where it is now), NYC, and Dallas.
Then sit back and wait for ACC to fold in 2020-whatever and pick off some of the aftermath. Maybe bring in Houston and/or BYU to supplement an addition of 2 or 3.
If there aren't enough slashes, here you go...
