10 to 13 or so years ago there was talk that it would happen. However that was when there was a staff besides just HT. Also I believe that some people in the scenario terrain team were likewise working on it. Most of those people are long gone now. I also think I saw a screen shot of a Japanese CV, but I been in a semi-coma since then so my memory may be wrong.
Heck most people would never imagine the game would still be rocking 20+yr old 3d models for the Tempest mkV. Alot easier to do than a full blown carrier.
