If I remember correcly, equinox is a terrorist group that want to create some kind of technological revolution within the human sphere ? If yes, I would imagine a sectorial based on some underworld/criminal element (bounty hunter, brawler, securitate, aida swanson...) and some strange/amoral tech (morlock,"brain in a jar" hollow men,kuang shi...)
Looks like a list of employers rather than playable factions, but those Ladon guys could be an interesting playable faction, particularly if they come with CSU Fireteam Core... (but oh man, the book-keeping!)
There's no fireteams that have anything like Meta-Chem, Booty, or similar. they could do different ones that don't have it and can fireteam though.
Well, CSUs are in a few but with a max of 2 so it doesn't get too confusing. I try to avoid more than 2 metchem/booty models in a list due to the book-keeping, so a new metachemless profile would be neat, kind of a CTU or "Corporate Tactical Unit" type thing that also gets some heavy weapons.
Uprising suggests that the Yellow Banner is Earth, Red Banner is Mars, Green Banners (plural) are Paradiso, White Banner is Huangdi/Svalarheima. It's really sounding like PanO is all privatized, but don't hold me to that.
