Dorg, stop trying to do it in 1/6th and think smaller. you want to do some DKOK and other guardsmen? medicom makes some 1/9th scale figures. look into those for the base bodies. OR look into using the DID children bodies.
Just because it's 12 inches doesn't make it 1/6th. I've got a Figure of Optimus Prime that's a foot tall, is he 1/6th? stop thinking inside that box, and start thinking outside it.
you're GREAT at thinking outside the box usualy. unshackle your mind and get creative with what you CAN get.
