Yea, roughly a third of neophyte hybrids mature into builders that are much less dangerous in the short term but in the long term might present you with megaproject-esque defenses
They pick up construction modules from a construction module factory, travel to target system (if it's not the same), and then the construction module will "charge" build points over time; when it's done it creates a self-building structure (much like if you had placed one, but controlled by the hybrid's controller).
This method could be adapted for the the trader, but it would still take work (the trader is not an AI unit, for one).
