That is actual, proper, honest-to-gosh-darn genius!
I'd like to have a crack at doing the full-scale version myself, since I now have a spare semi-repainted Hot Shot. With orange arms, actually.
The only real difficulty I see with the upscale is regarding the forearms; these ones don't bend, so you don't need to worry about the elbows and fistsgoing the wrong way. The Cybertron version might require a bit of re-engineering in that area to make it work...
