I wonder if the 14 graphics engine can do something like this.

China would like to chime in here perhaps?

The game isn't sold in China, at least not SE's version of it.

Doesn't China have a different build?

Yes. The Chinese version of FFXIV is produced and run by Shanda Games. They license SE's game software to use as their starting point, but then they modify it to suit a Chinese audience, not only by translating the game, but by adding, removing, or changing items, enemies, and some parts of the storylines. If they have an issue with an outfit, they simply wouldn't include it when building their remake.
