Schools that line up a new conference would lose their vote on the matter to disband. Unless all 14 schools plus ND are going to the B10 or SEC, this is less likely to happen than the ACC extending their current deal for another 20 years.
With the Big10 & SEC media rights deals not expiring until 2030 or later, there is no urgency for the ACC schools to make dissolution happen. Sure schools like FSU, Clemson want it to happen ASAP, but they don't have an impending deadline imposed on them like USC & UCLA with the Big10.
I feel Clemson, FSU and other ACC school's process is opposite what OU, UT, USC and UCLA did. They will break their conference relationship first and then find a new conference. A "build it and they will come" approach. If FSU, Clemson, UNC, etc are free agents the Big10 and SEC will be there to recruit them to their conference.
The below is from Ross Dellenger's article today:
A subset of seven schools in the 14-member conference has coalesced over what many of them describe as an untenable situation. Officials from the seven schools, led by Florida State and Clemson, have met a handful of times over the past several months, with their lawyers examining the grant-of-rights to determine just how unbreakable it is.

It sounds like the group is bigger than just the handful we traditionally hear mentioned (FSU, Clemson, UNC, Miami) and it doesn't sound like they are acting in isolation.
If the group is that big, that's probably not meaningful in breaking the GOR. But it could be meaningful in getting unequal revenue sharing of the 12 team CFP money the conference receives. Those monies can't completely narrow the gap, but if a playoff team gets an extra $15-$20M, that would narrow the gap significantly.
Lastly, I feel like people are falling into the money narrative trap: "Having the most money guarantees winning". While more money definitely make running an Athletic Department earsier, we see examples in sport everyday where lower revenue teams have high-level success. Iowa State won the CyHawk this year and our athletic department revenue is 2/3's of the Hawks. How many times have the Texas Longhorns made the CFP? Cincinnati Bearcats made the 4 team playoff. Even at the professional level teams like Oakland, Tampa, Milwaukee have had equal or higher success as mega-money teams like the Yankees, Dodgers, Mets and Red Sox.
