In my honest opinion, this is a great concept that was added into the mod, and maybe it could be transformed into even something even bigger... First, add a 'flying' space shuttle to travel over the space, in the dimension of the 'space station' , and make able to build different space stations, that require different types of materials . Each space station over a specific planet should meet different requirements, since not all planets are the same right? And add a little world generation to the 'space station' dimension, like orbiting asteroids or such, or even OTHER spaceships! and add mobspawners and such... imagine space pirate creepers! Oh my! tl:dr add features to space station dimension and make each differentiate from each other depending the planet.
