I doubt it would be tops on anyone's list (manufacturers, I mean), since most of Japan's carriers were unique designs. MOST, I said. There were a few that were supposedly of the same class (most notably the Taiyo class of light carrier), but since companies tend to thrive on reusable molds, like the 4 Iowa-class BBs or the Musashi/Yamato, they wouldn't be able to reuse as many molds for the carriers. They might think about doing the Shinano, since they could probably use the Yamato hull, at least - and possibly the Zuikaku/Shokaku. But there probably aren't enough repetitive classes to make it financially agreeable. But we can still hope - the Takao class is coming out now (I mean soon - it technically isn't late August yet) and we're seeing earlier classes of US battleships (South Dakota class). Even though both issues are repetitive (each have 4 ships in their class) they are still new kits in 1/350 scale, so there are changes in the wind. And the I-400 just came out, so that's another good sign.
I'm not saying it won't happen - I'm just expecting that they're more likely to issue an Independence-class light carrier, or a Kongo-class battleship, before they move on to the much more unique carriers. I wish they'd do their market research on these boards, though - then they'd know how well-received any new 1/350 design would be!
I'd love to see any of the Japanese carriers in 1/350 scale - I'd also like to see the pre-WW2 US battleships in the same scale. Imagine having to deal with cage masts! Oh, the exquisite frustration!
