I'd recommend you call TakaraTOMY. I've always found them to be easily approachable, polite and efficient in addressing any queries/comments. The worst thing they'll tell you is to talk to Hasbro... but you might as well try to talk to TakaraTOMY first since they've always been the ones who've conceived/designed every Masterpiece toy to date.

When it comes to Masterpieces and reissues, Hasbro has always been reactive and never pro-active. Look at the history of every Masterpiece and reissue that Hasbro's ever done, they've always - without exception - been something that Takara(TOMY) did first. Hasbro may tweak something here or there to suit their market or even try to make an improvement, but they've always been reactive. So considering that Hasbro's never been pro-active with Masterpieces before, I highly doubt that they're going to do so for a MP Galvatron.

But if you really want to give it shot, then give Hasbro's RI main HQ a buzz. But I should warn you that whenever I've tried calling them I've always gotten an automated voicemail response -- but if you like you can leave a recorded message for them. That's another reason why I'd recommend calling TakaraTOMY first... you actually get to speak to a human being! (特に日本語が分かれば問題ないでしょう )

Anyway, if you wanna contact Hasbro, here's their number:
0011-1-401-431-8697
I'm guessing that they're open during trading hours on weekdays, and their time zone is -4 UTC. Their Customer Service line is open Mon-Fri 08:00-20:00 EST (they're currently in EDT) and Sat 10:00-18:30.
