>>5872876Let me tell how I've had done it.
Scrapped the crystal piece and used the mold to make a ccbs version of the av-matoran arm instead. Essentially an angled bone piece with addon ports and no extra balljoints and used that on the legs instead of the ugly technic mess that's filled with red axles.
For head I would had gone with more streamlined look that hides the jaw of the head underneath and made it so that the top of the mask is hollow enough so that you can snap the jaw by pushing the eyestalk but the mask doesn't pop off.
This whole configuration would use less parts so the remaining bits would had been used on fixing the other flaws of the sets.
