I might just try that....
BTW, im guna try the arm conversion for the claws sometime today. Expect pics
UPDATE: OKay, so no pictures today. Iv made the model, as in grafted the Claws onto Power Armoured arms and drilled holes in the fists and backpack for me to feed guitar wire (which i have also got and cut to the right lengeth) through. Looks pretty badass, however i have ran out of glue (

) and so can't glue the buggar together yet.
Soon as i get some Imperial approved Superglue, i'll show you the results of my fiddly thumbs and sharp blades.
