Yeah, I have about 6 Halo 2 figs. In fact, on one of my ARC pics on my custom page, Tarturus is in the back
. Anyway, to get back on topic, some Star Wars people would look pretty cool in their Crimson Guard helmets. Though the bodies don't look half-bad, I like the buttons on the front of their torsos. Maybe if you change their head somehow, and paint it completely black or with some gray/brownish highlights, they could be some kind of Star Wars thing. I don't know, good luck experimenting.
