Thats a good idea, it sounds polished, and realistic.
But I don't think you understand what I mean.
Like a door, there is a break in the rock barriers and you can see a path going down. And it says Korriban Canyon or whatever.
Kinda like mods that use the korriban cave exit, the only difference is that you're MAKING the exit through module editing......
However, thats my personal opinion, your idea sounds good too.
