Totally necro'd for reasons (good existing discussion, no more recent similar threads - Redesigning space stations is more about the stations themselves).
What I would like to see is a more "natural" distribution. According to Trello, global/npc factions are a planned thing. Presuming multiple factions on a server, it would be preferable to have the server generate density nodes of activity that sort of "push" other factions away; Trade Guild "Core" systems would have little to no pirate presence, while a Pirate Clan core system wouldn't have any Trade Guild presence. Pirate-type factions would generally avoid more developed Empire-type factions but cluster closer to Merchant-type factions. Pirate factions would also have a scattered presence in void systems a few systems away from star systems.
However, past that, the total number of stations would drop drastically with a maximum of 2 stations per intergalactic system (5+ void systems away from galaxy borders), and even that could be something configured at world generation - how "empty" intergalactic space should feel. It should also be a configured setting as to how "settled" further galaxies should be - Have the empires, pirates, or merchants bothered to traverse that vast gulf, set up warp gate networks, and establish a lasting presence? Might there be new factions a few galaxies over that are entirely alien to the starting ones? WHERE DOES IT END?!?!?!
Just my thoughts. Generally, I agree that intergalactic void systems should be pretty empty. Maybe a few asteroids here and there and the occasional station once there are a few void systems between it and the nearest star.
