I wonder if the foursome would be Texas, Oklahoma, Kansas and Florida State would that be better than any other combo. Kansas would be a better upgrade to Texas Tech, assuming that UT can leave TT behind. It would come down to between Kansas and Clemson. Clemson is more regional to the original SEC schools but Kansas has that brand power that the SEC would love to boost its basketball acumen and would have to leave K-State and I-State behind, whereas Clemson would double up in a small state.

Not to mention side stepping the second-school issues in Texas and Oklahoma as well.

Also, Florida State has steadily improved their basketball since joining the ACC, so they can slide right into it and compete for titles straight away.

Division-wise, this makes a whole lot of sense:

Kansas, Missouri, Texas, Texas A&M, Oklahoma, Arkansas
LSU, Mississippi, Mississippi State, Alabama, Auburn, Florida State
Florida, Georgia, Tennessee, Vanderbilt, Kentucky, South Carolina

All the "newbies" would stay in the West and not have to intrude on the original members until the conference playoffs, basically a truncated Big8/SWC division and regional rivals put together.

Whatever is left of the ACC would look at USF or UCF for potential replacements.
