I think he needs to remain at catcher as long as possible to have a chance at making it in. As a catcher, his numbers and his value are astronomical. As a first baseman, or even third basemen, they'd merely be very good. If he's able to catch half of the season for the next 4-6 seasons, while still maintaining a high average, OBP, etc., I think he gets in.

Pretty sure Kenji Johjima also returned to Japan after struggling in the big leagues. Him and Meche were the only people I could think of.
