If this was a mod, I would play the hell out of it. My friends and I would talk about the same thing after watching episodes of the Pacific. We thought a Japanese faction would work if it was against a US Marine faction whose primary objective would be bulldozing the thick brush past the beach and then it would be a meat-grinder of booby-traps, mg nests and banzai attacks. US could only deploy units onto the beach from carriers and could get shot down while the Japanese would have inferior units but great numbers and a hell of arty.
And of course, the US would have to have an ability to call-in John Basilone and upgrade him to hold a Browning.
Probably won't happen but it is fun to fantasize.
