I agree that is a hole in their first party line up that they are missing. If I were them I'd design a JRPG studio around the Atelier Team (like them, not buying Gust). A smaller cheaper studio making games that are profitable after 100k sales. Not every first party studio has to be a huge budget affair, sometimes you just want to fill a niche that some people enjoy to keep them coming to your system. Do that with a studio that also makes you a little profit and there really isn't a down side as far as I can see.
That's all to fill the JRPG hole obviously, I don't really but I'd do something similar with WRPGs. Keep things cheap until the team establishes themselves, if they get a good fanbase going that warrants an increase in budget then go ahead.
