You know the GeoCorp scoops? I often use them as doors for techs to have other techs inside, but they are not very efficient. Could you make something like those scoops just as GSO, and replace the scoop itself with a door? I've heard something about "roadblocks" or something allowing techs to move on each other, and in combination you could make mobile garages with doors and stuff. I am currently making an AC-130, a huge plane with a 7x40 cargoarea, where it would be awesome to have a functional door, and perhaps even a ramp, and then drive other techs in using these roadblocks. I know it's much to ask for, but if you give it enough time, it would be a game-changing addition.
