I had an idea to take the WST Megatron and kitbash him into a mock up of Shockwave. I've wondered if anyone else did this, and if I could get some pointers for a customizing newbie. So far the only impediments I can see are that Shockwave's barrel forms his arms as opposed to Megatron's back, and Shockwave should be taller than Megatron. It wouldn't be quite accurate, but worth it for a Shockwave.
