Yeah, ankle tilts is about the only way I could think of to improve the figure, though like most he stands just fine without them. I guess there is also some degree of partsforming to it as well, which I've always been fine with. It's difficult to see how you would remake the toy without that, but for some it could be considered a down score.
I wonder how hard it would be to track down a Hybrid Style Galaxy Convoy, UltimateGalvatron?
