I really like the idea of personalized armor for Freelancers. Since they're based in the central city, and thus are something of a balancing act between the Minds, I would advise a Black and White base uniform (Yin Yang). I can also see recruits from, say, Obsid adding a dragon crest to his helmet, or one of Dekonio's wearing a green and brown surcoat.

Question: How well-known is the Freelancers? And what do people think of them?
