Is one of the most famous palaces in all of Chinese history, and is the largest preserved royal palace complex still standing in the world, was constructed from 1406 to 1420, and was the imperial palace and winter residence of the Emperor of China... and it will look really good on cubes, will be marvelous on domination, also it's pretty famous, so will be easy to build over existing maps.

Afaik Vilaskis dont actually create maps based on a specific thing in real life. He has like a few different ideas and inspirations to every map. You can't look at some map and tell exactly where it's located. So I doubt something like this will be added to the game.
China theme? - Yes, maybe.
Some historical structures, places, almost exact copy of something in real life? - Eehhh very unlikely.
