I like the idea, touches on the other more subtle side of the syndicate than traitors tends to. To throw in my two cents, maybe give them less military grade equipment and more along the lines of traitor gear. They are meant to not be connected to the Syndicate. Also, would they really bring a blob onto a station when it could easily spread back to their outposts once it matures enough. Also, maybe they could bring some horrible disease to wipe out the populace of a station for later looting. (Plus some kickass armored biosuits would be great
