Wouldn't the HQG1C group need a sacrifical Takara in order to make the mold? I guess that could happen if someone happened to have a baity one they'd be willing to give up...But the moldmaking process would probably be more expensive than normal, since it's jointed. It wouldn't be in just two parts like most ponies are.
My mom lived in Japan in the 80's, she'd never heard of or seen Takara ponies. I think everyone else is right. I can't see this doing well being distributed on a large scale.
