Having done a bit of research as I have been having fun designing ships, I have discovered that it would be pretty easy to make Scum more than just a catch-all faction. There are 3 large criminal organizations that could be quite easily represented as sub-factions, and moreover, open up some design space for sub-faction specific ships:
Black Sun:
- CloakShape fighter
- Ixiyen-class fast attack craft
- Kihraxz-class light fighter (technically, this ship is EXCLUSIVE to the Black Sun syndicate}
- Vaksai
- Rihkxyrk-class assault fighter
- StarViper-class attack platform
- Supa Fighter
- Y-wing starfighters
- Z-95 Headhunter
Hutt Cartel:
- Alpha-3 Nimbus V-Wing starfighter
- CloakShape fighter
- G1-M4-C Dunelizard fighter
- HH-87 Starhopper
- Intruder-class starfighter
- M12-L Kimogila Heavy
- M22-T Krayt Gunship
- M3-A Scyk Fighter
- Skyfighter
- Y-wing starfighters
- Z-95 Headhunter
Zann Consortium:
- StarViper-class attack platform (equipped with buzz droids)
- StarViper M-2 fighters
- Skipray Blastboat
- TIE/LN starfighter (originally Empire)
- TIE/sa bomber (originally Empire)
- TIE/D Defender (originally Empire)
- A-Wing (originally Rebel)
- Rihkxyrk Assault Fighter
The Zann stuff would be kinda crazy fun in terms of mixing up a bunch of stuff that is traditionally unaffiliated with each other.
It would seem like a great project that could be a card pack that re-organizes the existing ships into the new sub-factions, supported by brand new ship releases.
