Kubo does not own the rights to the anime, therefore he cannot simply take his manga to another studio. It would have to be sold to TV Tokyo by the studio that is currently producing it — and that is not likely to happen. The anime wasn't popular among Japanese fans, so it was canceled. The manga suffered a similar fate, so there really isn't much of a chance of an anime making a return.
