I actually, despite station competitions some time ago, suspect that we'll need remake of the stations to fit all the new mechanics etc we'll get without it being half-assed. Due to said competitions being pre-rail, most constructions while aesthetically pleasing already seem a bit crude and dated.
But yeah, I guess that once we'll get NPC/mobs polished a bit and demand bigger constructions put on the system optimized further, sticking in a trader or two, some quest giver, a few patrolling security folks and generic, aimless station dwellers would be nice.
