This can be accomplished and I agree this is the general idea. How? Promise ESPN more high revenue games- Clemson-ND, Miami=ND, FSU-ND, NC-ND (event though I'm not seeing this as a great matchup, they are considered a brand name and at least if Billy B is the coach people will tune in). Maybe add a ninth conference game as well, or some sort of ACC-$EC challenge in football.
I don't think any of us know exactly how this happens, but agreeing to alter the schedule and probably let ESPN schedule some of these games could garner enough to maintain current payments but add 10-20 Million each for the top brand programs.
