Toynami have the worldwide, including Japan, rights to produce Mospeada toys, rights gained via Tatsunoko Productions in Japan and Harmony Gold everywhere else, so any Inbit toys would have to come from them. Yamato chose not to seek the license, so don't look to them as white knight for Mospeada fans.
The Matchbox/Playmates/Harmony Gold Invid Shock Trooper toy is one of the most imported pieces of RT product by Japanese Mospeada fans, simply because there is nothing else that comes close, and it's a passable representation at best. While fans in west might not be happy at Toynami making another run with the molds, a Mospeada branded versions released via Epoch in Japan might clean up.
That said it literally TOWERS over the MPC Alpha, and is seriously out of scale against the larger Gakkens too...
