Well that's just the point, much of that sort of modding isn't as popular or up to date as one might expect. The only two contenders for re-balancing and slowing down combat is Three Dragons and Under a Red Sky.
As for "capturing the atmosphere", I've been studying the matter a bit, and have concluded that CA have captured and embraced the unique cultural hooks of China's relationship to this part of their national history and mythology, very well. They clearly put much extra effort into their research from the concept phase forward.
The problem is that what the Chinese want to prioritize in a 3K title isn't the same as what works for westerners.
Were it for me, it would be more realistic, with a very calm Art of War, Sun Tzu, vibe. As a white male american, I'm confronted with the discomfort of NOT being catered to, for once. But that's my problem. Clearly not CA's.
I'm mostlybecause I'm so spoiled for a vibrant modding resource, and finding it not being represented in places I'm used to.
