I very much doubt they're using exactly the same CAD on these toys as the originals. Once they change anything to the CAD there's no longer a benefit to copying the 'old CAD'. I think it really is more a thought process like "Yamato had this on a much cheaper toy, we need to have it on our super expensive toy." I don't think you can make an argument that something that necessitates another mold/part and additional assembly in any way would SAVE money. We're all paying extra for something that's only visible for a moment during transformation. Seemed silly on the Yamato toy... even sillier now. That said, it's not like I'd buy another one if this toy cost $5 less so that's probably just as good an answer as anything else.
