I doubt if everything would be the same in the garage after almost two decades, but it would be nice as I mentioned earlier if some of the lights were to operate in the same way and that wouldn't be too difficult to animate.
I don't think that people should be put off from suggesting the seemingly impossible as someone might find a way around such problems (though I don't see the change as important).
In that vein, I personally would love the Imperials to get ESB style haircuts, a real bugger to do convincingly but if someone could pull it off it would make them seem more cold and miltaristic, leaving the long hair to the Rebels (hairstyle cliches are a permissible form of character shorthand in my book).
