Due to the fact that the Klingon faction has a few races with special outfits like Orions, Naausicans, and Gorn. I think it'd be amazingly cool if Aliens could use those bits. They're not Klingons and it would show an alien species as being more attuned with one of the sub-faction's cultures. Like a race that was allies with the Naasuicans and have a pirate history with them, or a race that deals in slaves like the Orions.
The fact is the KDF suffers from a lack of costume options and more diversity can't hurt, it can only help. I wouldn't think that it would take to much to transfer those costume bits to aliens since all races (save Gorn) tend to be extreamly "humanoid".
