Well, knowing that TakaraTomy/Hasbro are likely not going to be putting out MP Megatron 2.0 in scale with MP10 any time soon, I figure I might as well try my hand at making one. I have a few MP Skywarps hanging around for this sort of reason! I sketched out a design on paper that looks like it might work out, albeit a little wide on the legs/handle. I figure holding him like a gun isn't a priority - as long as he can prop up in gun mode and looks right in bot mode, that's all that matters.
I disassembled SW and started on the legs. I cut out some styrene based from my sketch and it's looking okay proportion wise.
