Ah, so how would they work in the game?
AI races having just an MC on board right from the beginning?

We could implement this by making it a compulsory choice in the race trait screen to choose 1, and, eventually, after a long time, as happens in uplift, they change into new types of being and reach 'transcenence' and change in focus
Currently, you cannot
force the choice of exactly 1 trait out of N. At the moment, it is up to the host of the game to make sure the races uploaded are following the spirit of the mod.
Once racial traits are chosen, they cannot be changed.
However, it is possible for you to mod a super tech area, which opens once a player has maxed out on a special "transcendence" tech. That could start a whole new set of ships & components, or give an exact duplicate of all the original racial techs.
If I've understood your idea, then it should be possible, and require only a little "turn zero" trust when choosing racial traits.
