TCU would likely be the best fit football-wise, but Pac-10 would probably like to have as high a profile as possible basketball-wise to replace Arizona in such a scenario.
All that said, I still think a push for an eastern team makes more sense as well, they want to add a bigger population center/TV market and will "settle" for St. Louis if an eastern couldn't be met.
I think the most obvious one that I have heard was Mizzou to the B10 (new name?), Houston to the B12, then an overhaul of the MWC, adding Boise State, Fresno State, and Nevada, and making it a BCS Conference. If the B10 were to add Mizzou, I would see the alignment like this...
Obviously the East would be favored in football matchups with the big 3 there, but Iowa, Missouri, and Wisconsin (Illinois some years) could provide a formidable opponent. The problem with the North/South alignment is that OSU and Michigan would be in different divisions, and that won't happen. That would cause a possible rematch of The Game in the conference championship game, when (if?) Michigan returns to prominence, and that won't happen.
