According to JR elsewhere, here are the teams in the ACC ranked by value returned to the conference:

Clemson / 26th nationally in Revenue / 1st in the ACC in value added
Florida State / 10th nationally in Revenue / 2nd in the ACC in value added
Virginia Tech / 46th nationally in Revenue / 3rd in the ACC in value added
Georgia Tech / 60th nationally in Revenue / 4th in the ACC in value added
Miami / 29th nationally in Revenue / 5th in the ACC in value added
N.C. State / 56th nationally in Revenue / 6th in the ACC in value added
Louisville / 15th nationally in Revenue / 7th in the ACC in value added
North Carolina / 35th nationally in Revenue / 8th in the ACC in value added
Virginia / 36th nationally in Revenue / 9th in the ACC in value added
Syracuse / 59th nationally in Revenue / 10th in the ACC in value added
Pittsburgh / 45th nationally in Revenue / 11th in the ACC in value added
Boston College / 57th nationally in Revenue / 12th in the ACC in value added
Wake Forest / 61st nationally in Revenue / 13th in the ACC in value added
Duke / 33rd nationally in Revenue / 14th in the ACC in value added

Looking at that order, who do I think could plausibly generate $100m in the SEC? Clemson, Florida State, Virginia Tech, Georgia Tech, Miami, NC State, Louisville, North Carolina. If you have to bump somebody in that group to make room for Kansas in a 24 team SEC, it's likely Louisville. Not because of their performance or academics, but because Kentucky does not want them in the SEC. I think if Louisville is left behind for Kansas then Louisville will be one of the flagships in the Big 12 in the long run.

Wildcards:
- If Kansas goes to the B1G and the SEC and B1G and their TV partners both agree Missouri makes better sense in the B1G then (because it would), that frees another slot for Louisville or Virginia.
- I think Wake Forest and Duke could be non-football members of the SEC if Vanderbilt takes the same path. (Your final non-FB member would be Rice or Tulane in that scenario) That's almost ideal for Duke, as it gives them the excuse to Deep 6 the football program they've never really cared about in the first place. It would be a tougher pill to swallow for Wake, who actually does try and punches well above their weight on a consistent basis. This scenario also frees another slot for Louisville or Virginia due to Vandy.
