They already do that in a way, at least for Florida residents. The more you pay, the fewer blackout dates you have. A lot will depend on when SWGE opens. If it is close to a normal blackout period, I would definitely expect the blackout period to be expanded. I also wouldn't be surprised to see some limits on FP+ when it first opens as well. Then there is always the option of increasing the price on the one day ticket at DHS to encourage people to visit the "less expensive" parks, similar to what they have been trying to do at MK. They will have a better idea of crowd control once it's open at DL and they get some real life experience. Right now, everything is speculation.
