What is the source? The actual agreement in place as of now. Research them, I am not doing the work for you. The work has been done in this and other threads.
Agreed, the issue now is a settlement, Please explain how spending a few million dollars more is not worth several hundred million or more than a billion dollars, should enough teams leave.
As for the exit fee, there is no need to negotiate, FSU was one of the major proponents for the current exit fee, which is well documented. Courts are not likely to allow decrease the amount to their benefit harming the remaining schools. ESPN owns the rights to FSU and must pay the ACC for FSU's rights. ESPN cannot simply move them to the SEC, that would be a criminal act and make the remaining ACC teams very rich. FSU cannot simply play for the SEC as the ACC will receive the revenue.
Anyway, have fun when you get into a contract dispute.
Sure, anything may be agreed to but you have failed to show why any ACC team would vote to reduce the costs to FSU without gaining anything in return from FSU.
