Yes, "drone fireworks" as they are being called by many towns are replacing traditional fireworks.
Disney has already dabbled in the use of drones for nighttime entertainment so I wouldn't rule it out in the future.
AK would be the perfect place to have it, for the animal reasons and would certainly be a boost to nighttime shows. Maybe part of the inevitable replacement of RoL.
I don't think they need anything at FW and likely the availability of enough open viewing space would be a problem.
In 2016 Disney did request a waiver from restricted air space to fly drones over the parks from Federal govt and was approved so it could happen.
