"Mecha musume" does this with military hardware. Strike Witches is an entire anime dedicated to combining WWII pilots, their aircraft, and pantsu. Chuck Yeager is in it. I think someone told him.
In any case, this is not the cutest set of pokegirls I've ever seen. I will communicate my disappointment to the moe-foundry, the demon factory that belches black fumes from iron chimneys shaped like cat ears.
