Sorry to butt in like this. But i tried to follow this thread but could'nt quite grasp it. What mongol threat are you talking about?
Before i digress and go into a longwinded session, let me ask you this, in game terms are you trying to replace the manchus.
They appear way too early as a nation. The Jurchen tribe which became the qing or Ching(It sounds like Chi'ing in chinese which means "Pure") dynasty or manchus did not become a regional power till 1620's.
And here is the long.... version.
The Khitan(eastern mongols) rose to power forming the liao dynasty. The jurchen tribe(another eastern mongol tribe) helped the northern Sung in destroying the liao dynasty, turned around against their former friends the northern sung, forcing the emperor to flee to a new capital forming the southern sung dynasty and in turn forming the Jin dynasty.
Chengis Khan first defeated the jin and then the southern sung forming the yuen dynasty.
After the fall of the yuen dynasty, mongols in inner mongolia and much of the outer as well had disintegrated back into tribes. Tribes that consistently raided the border areas(villages and towns). The great wall was strengthened and extended by the mings as a deterrent to these raids(and ofcourse a show of power and grandeur) rather than a fullscale invasion. They also did military expeditions (one of them - burning the former imperial capital of karakorum) bringing all of inner mongolia and north west china upto tibet under their control.
In the early to mid period of the ming dynasty the mongols had the Oyrat alliance, a tribal alliance to be precise, taking control of the trade routes outside the great wall. It disintegrated with the jaljas taking control in outer mongolia and the khalkhas in inner mongolia.
The later ming period was full of internal strife allowing the jurchen to filter back into inner mongolia. They quickly united the tribes and took control forming the "later jin" dynasty which was renamed qing or ching dynasty. During this period they also assimilated chinese culture, food habits; philosophy(confucianism) etc.
When beijing fell to a peasant revolt, the emperor committed suicide throwing the whole country into chaos. A ming general threw open the gates at one of the important passes allowing the qing to walkin and take over beijing.
The later jurchen a eastern mongolian tribe were also called manchus.
Inner mongolia today is an autonomous region with Hohhot as its capital.
So much for the official version.
Here is another take on the whole deal though. I have cut and pasted it from an article.

Inner Mongolia, as a part of the Great Mongol Empire, was never a part of China.
From the day Genghis khan founded the Great Mongol Empire in 1206 to the death of the last Grand Khan of the Mongols---Ligdan Khan in 1634, the Mongol nation had been an independent state for more than 400 years.
During the Ming Dynasty of China (1368-1644), there were many wars between the Mongols and the Chinese trying to rule over each other, but the China's dominance had never reached beyond the Great Wall. Once the Mongols even captured an Emperor of China. (In 1449, Esen Taiji defeated Chinese army near Peking and took Chinese emperor Ying-tsung (or Ying Zong) prisoner). Also during the Ming dynasty, Fearing from the Mongol’s invasion, China took great efforts to rebuild the Chinese ancient fortification ---the " Ten thousand miles of " Great Wall. The Mongol Empire lasted outside of the Great Wall until the Jorchid (later known as Manchu) people took over the entire Inner Mongolia in 1634.
During the Manchu rule, the Mongols never had given up their effort to get rid of the Manchu domination to reestablish an independent Mongolia. Galdan Boshogtu (1645-1697) of Dzungar Mongol once succeeded to unite all the Dzungar Mongols (or western Mongols) and the Khalkha Mongols (Outer Mongols) and almost seized Peking, the Capital of the Manchu Empire.
In 1644, Manchu people succeeded in controlling China and Emperor Shuen-chih (or Shun-Zhi) proclaimed the Great Ching Empire (Tai Ching). So we have enough reason to say that Mongolia was not a part of China during this historical period because Mongolia (Including Inner, Outer, Dzungar Mongols) and China were both ruled by a foreign nation during the time of Manchu Empire. Chinese people didn’t have their own state or government, and China, just like Mongolia, was a part of the Empire established by the Manchu people.
The guy really seems to take exception to mongols being called part of chinese empire.
