Here is the problem as I see it. Empty trains on windy days have valleyed twice. They have since added a device to help with this, but not really solve it. So, any possibility of valleying after the non inverting loop (where it has happened twice) means that with full 7 train/moving platform operation an e-stop is guaranteed to mean getting riders stuck and needing to be evacuated from the 90 degree, straight up lift hill. The original design would have allowed the car on the lift to lower back into the station, but during construction a late decision was made that changed from two lift chains to anti-rollbacks. Now the danger is greatly increased because the car will have to be brought up to the top to be emptied, also meaning that it absolutely can not ever pass that point because if it did it would collide with the valleyed train.
Changing the lift design from 2 lift chains to one with anti-rollbacks was, in my opinion, the reason we may now never see that platform move.
I should note, plenty of internet hearsay claims that the ride has been tested many times overnight with the platform, but that still doesn't mean they are going to be willing to risk it with trains full of guests anytime soon.
