I think that eventually Disney will come up with something that might be called Genie Ultra, because no matter how G+ and ILL$ will work, both still have restrictions, the biggest being you can ride each ride only once. The next-biggest restriction is having to use your phone all the time, trolling for LL selections at times that are at least somewhat convenient for you. Not to mention having to get up at 7 a.m. while you're on vacation.
With Genie Ultra, though, you wouldn't have any restrictions--well, not as many anyway. You'd be able to ride anything and everything except maybe Tron and RotR--those would be limited to twice each--and you wouldn't have to make reservations for anything. Just having Genie Ultra would give you access to the LL, like getting 100 anytime FP+s for the day.
I'm thinking this would cost about $250/person. Maybe that's too low. And there would be a limited quantity of them, like the front-of-line passes at Universal, which are also limited.
Do I think people would buy this? Absolutely. Something like this would completely eliminate the stress of standing in line, the stress of getting up at 7 a.m. and not knowing whether you were going to get the ride(s) you wanted at the times you wanted, and the stress of coming up against some restriction or requirement of G+ or ILL$ that you were unaware of.
