Yeah, accordian doors would work.
Also, to return to yesteryear, a classic space design is to use the 1x2 x 1x2
brick hinges to open up to equal halves of the back of the ship. I supposed
that could be applied to bay doors that just swung outward. I was thinking
that any entry guidance equipment could be located on the inside of the doors
themselves, thus having such equipment be pointed outward when the doors were
opened, and naturally guiding the ship inward as they close.
But I suppose folks want a cleaner, smaller profile when opening those doors
so that they don't get blown off. I've never done it, so my design is indeed
suspect, but you could make tall, segmented doors 1 stud thick, each segment
being 2 or 3 studs wide, that use the same 1x2 x 1x2 brick hinges, sit them on
tiles, and have them scoot sideways; like a rolltop desk cover but sideways.
Though you'd hafta make any corners navigable by introducting them at less
than 90 degrees.
Part of a possible door track:

My ASCII art is poor here, but you could use those 3x3 diagonal bricks for use
as track guides on the diagonal portions, and 1x1 tiles along the track in
those diagonal areas. I'm using 3x3's because I couldn't think of anything
that would make a nicer outer curve of doortrack (short of nice pieces no one
would ever want to use as a mere doortrack). Inside the door track, one could
easily use those 4x4 quarter-circle bricks.
The goal is to reproduce pieces that have already been made (the sliding
garage door pieces of old, but going sideways instead).
If someone tries this, LMK how it works out.
