Mags, I warned ya! This is what happens when you inspire me! Now I'm up 'til all hours of the night kitbashing.
Mags reminded me of a few Star Wars novels where Han Solo goes to look up some old smuggling buddies. They're on an asteroid that's been bored into and modified to be a space station/smuggler's den.
With the blend of natural and artificial terrain, You'll have regular CaveWorks stuff and full-blown First Light sections all to themselves.
But what about those areas where the two terrain types meet? As you venture through the base, you're bound to find areas that cross the line, and have technology built right into the very stone foundations of the asteroid!
Start with a normal FL door, but cut it to the width of the outside of the door slider frame.
Next, cut off one of the caveworks tunnel section ends (the outward facing one. Leave the inward facing side alone). Glue it on top of the FL door frame.
With the door out, you'll notice there's a bit of overhang of the cave creeping in at the bottom of the door, for a nice ambiance.
Then glue the whole thing onto the tunnel section's end.
Once it's on, you'll have a choice as to what type of flooring to use, depending on how "rustic" you want it to look. For the FL floor, just cut out an appropriately sized section of an FL corridor. (I modified the file in PS to save on ink.)
I'll probably glue the natural cave floor to the tunnel section, and keep the FL corridor floor as a "drop in" mod.
