Ok... plagiarizing from Bliz again,
When planets come back, give some planets NPCs. The NPC will build starbases, shipyards, defenses, ships, etc (at about 1/2 speed). They start out neutral/aggressive to everyone (1/2 the distance from furthest NPC ship to their planet is aggressive boundary). If you defend (attack an attacking ship) a ship, shipyard, etc, you gain faction. You attack their stuff, you lose faction. With enough faction, you become their allies.
On the flip side, if you conquer their planet, you gain all of their (remaining) ships, shipyards, starbases (as NPCs).
