We already have a "universe" racial trait that sets things such as shields, propulsion and weapons AND a "race" racial trait that adds things such as ship hulls and some exclusive components. For example imperials have green firing lasers on their star destroyer hulls and the rebels get red-firing lasers on their mon-cal cruiser hulls.

As for the number of races, yes we don't want to have too much, I don't think we'll have more than 5-6 races (at least in tech means) in the SWmod2.
I think that by the time we get to star with the crossover part we may only pick the major races for each universe, plus perhaps an additional trait similar to the sw-outlaw trait for minor races.

I like the idea of 'invisible civilan ships', maybe even the Rebels should have some.
