You could always make a script or command chain to spawn them. You'll have to find a system and give them a planet by making a colony and transferring the market to them or doing so by command I forgot it's been a hot minute.
The main issue is that resurrecting the mod at this point would need someone to retrace all my steps with fixing bugs since the last official version, and then also fix whatever broke in the most recent version, unless you were going to work solely with decompiled code. Either way it would be an enormous pain in the ass; you would be better off just writing the colony code fresh at this point, especially since the other big feature (bounties) has been taken up by magiclib.
Oh I wasn't saying that to you since I already knew your stance and situation on the mod being updated. I was just pointing out to anyone who still uses the mod with a version change or if someone wants to make a small script mod for that to spawn them.
Edit: Anyone seeing this do not use this with AOTD it will crash your game cycle 207 an onward due Vayra's factions unable to parse aotd's industries. Disabling popular front or the factions in the config will not stop this by itself. You must also go into mods\Vayra's Sector\data\config\vayraColonies.csv and set all to FALSE.
