@LT - nice work there! I've got a couple of scratch-warhounds in progress (torso done... legs/arms to go). Always good to see others' work to keep me going. Your troopers look great but aren't as mechanical as I'm looking to go. I'd like mine to be more abhuman (current servitors lacking a dynamic look... i think arco-flags are closer to where I'm going). I'm thinking several moving on mechadendrites, wheels, or tracks. Most wearing some sort of robe as opposed to armor.
@khaine - i looked at necrons as well as was thinking along the lines (thanks for the heads up on the size difference - didn't know that). Looking at the GK codex, yeah, i think coteaz/henchmen is a great idea. If I don't go with Coteaz, there's always the possibility of converting larger servitors (termies/strikes).
i haven't seen much in the novels to support skitari vehicles... so chimeras, storm ravens, LRs, etc seem hard-placed for the theme. Dreads are a straight-forward conversion. Can anyone point me to some fiction supporting vehicles?
EDIT: Digging around, the Necromunda Pit Gangers have some potential for modeling as well
