Have you put any thought in to this yet? I suspect it would be fairly involved to code, what with the variability of tech systems in Aurora, but some base line stuff shouldn't be too hard and would reduce the work load on generating a new race.
I'm thinking an SM popup that would let you set a race's ship size guidelines, ship speeds, favoured weapons, shielding/armour preference, etc., etc., then the program could look at the auto-researched tech, create some tech systems and knock up some initial designs that the SM can review and tweak.
Start with the easy stuff and give new races freighter, survey colony ship, etc designs, then expand on to creating their warships.
You could maybe create the warship designs on a fighting style, e.g. light, fast missile ships or big fast, armoured laser ships, etc.
