I like the idea...
PAC12 + Texas, TX Tech, Oklahoma, OK State, Kansas, K State, Rice, Tulane
Obvious candidate are the top 6 in the Big 12, but I think that both Rice and Tulane as AAU private a schools in major TV/recruiting markets will help offset the lack of markets and academics brought in by Tech/OSU/KSU.
Big Ten + ND, Syracuse, BC, UVA, GT, Miami
I think the Big Ten will let ND know that the ACC will be picked apart and add them first plus finalize their Eastern expansion by grabbing Syracuse and BC for total Northern dominance, then try for UNC, UVA, GT. But as most of us seem to believe UNC already has a spot in the SEC, however I think UVA would rather join Maryland and Penn St in the academically superior Big Ten than Kentucky, Tennessee, and South Carolina in the SEC. So after missing on UNC/Duke the Big Ten will still follow through with GT and try for FSU who will also likely join the SEC before settling on Miami who actually might be a better fit.
SEC + UNC, Duke, FSU, Clemson, VPI, ????TCU/WVU/Lville????
The SEC won't be the first to expand, but after the ball starts rolling they already have a plan in place which starts with UNC/Duke (who they almost took last year), followed closely by FSU/Clemson. They will offer UVA but I think they'll opt for the Big Ten and then VA Tech will be on deck who has been a better fb school over the last 20 years anyways. But after that I'm stuck.
They could go for Louisville, WVU, Pitt, NCSU, TCU, Baylor but no clear leaders are favored.
If UK wants Lville they'd likely get in, NCSU is likely out with UNC/Duke already in, Baylor will be vetoed by A&M but TCU (in DFW) could be a darkhorse candidate and help them get into Texas more for TV/recruiting. WVU was a candidate last time around and they could work, but I have no idea if Pitt would be considered.
Anyways here is my mock up with divisions.
West- UW, WSU, UO, OrSU, Cal, Stan, USC, UCLA, AZ, ASU
East- Utah, CU, KU, KSU, OU, OkSU, UT, TT, Rice, Tulane
West- Neb, Minn, Wisc, Iowa, Ill, NWU, Ind, Purdue, Mich, MSU
East- ND, tOSU, PSU, Rut, Syracuse, BC, MD, UVA, GT, Miami
West- A&M, LSU, Arky, MU, Ole Miss, MSU, Bama, Aub, (Vandy/TCU) or (UK/Lville) or (Vandy/UK)
East- VPI, UNC, Duke, TN, SC, Clem, UGA, UF, FSU (Vandy) or (UK) or (WVU)
