The are many options\choices for this to work and i think in time the devs will implement it.
I cant though fully comprehend why they still havent upgraded each npc BO race to have 1 space trait or somekind of space ability\enhancment. Like Saurians have Efficient.
Make say Vulcans\Andorians have +7 to weapons or +7 to Aux power setting (just a random examble), the possibilities are many.
This would make BO more valuable and allow us to have a variety of races in our bridge.
i can already imagine how this would work. they could even have a random selection for each race (vulcans for example might get a +1-2 to a power setting or havethe effecent trait) that way not every space trait is the same.
and as long as the same trait doesnt stack it would be nice
