ISU, KU, OSU, and TT are the biggest upsides from the remaining Big 12 teams, followed by WVU, K-State, and TCU (I truly believe Baylor is screwed no matter what).
ISU and KU have academics as an advantage, but in the antiquated “eyeballs in a TV market” fall short (although ISU has made headway in “total eyeballs” in the last decade).
OSU and TT have advantages in population, but their academics are terrible.
WVU has to hope the ACC is willing to take them, because neither the Big 10 nor the SEC will, and it’s their only hope.
K-State, similar to WVU, isn’t great at academics or population, but if KU goes to the Big 10 or ACC, K-State should get interest from the PAC 12 if they truly want eastward expansion.
TCU sits in the major DFA metro area, but their academics aren’t great and they’re a religious school, although they have gone more secular over the years.
Honestly, the best outcome for the most Big 12 schools would be if ISU and KU go to the Big 10, WVU goes to the ACC, and K-State, OSU, TCU, and TT go to the PAC 12. The biggest roadblock being whether what’s best for us is also best for those other conferences.
