I've mentioned it before, but it's really very simple how to add prequel/clone wars ships to the game.
Rebel faction becomes Light Side faction with subfactions of Republic, Alliance, and Resistance.
Imperial faction becomes Dark Side faction with subfactions of Confederacy, Empire, and First Order.
Scum stays the same. Although they could certainly do mando, black sun, etc subfactions at some point.
Boom problem solved. And it's not exactly my original idea it's basically how many multi era sw games work like Galaxy of Heroes for example.
