Honestly, as much as I want this, the changes need only be minor. Anything to keep Ming both interesting to play and tame during the game would be welcome. Japan needs to be subject to samurai shenanigans. India and Indochina are pretty much fine as is, but would be better if they didn't have to worry about China eating up the continent.
Other than that, the only REAL thing that needs to be done is modding to add 50+ nations in North America, Western South America and Western Africa. That all CAN be done and HAS been done in mods. In fact, I think most of the taming of Ming and Samurai-ing of Japan could be accomplished quite easily through modding.
One thing that needs to NOT happen though, given the new dynasty system, is China shouldn't be allowed to marry outside of China, but still needs a dynasty (for succession purposes). Not only historical, but would keep the game blob-free. This might be possible by adopting the tribal succession crisis system achieved from HTTT, but making it less...intense...
