there's a ton of problems with your suggestion.
a) This mod is based on the "Romance of the Three kingdoms" (i think) so the only major places where historical accuracy matters is the era and the overall ebb and flow of the war.
b) -once again this is a romance. historical accuracy to the fullest is more of an afterthought.
-Chinese government has always been different from western counterparts so i bet that one does not simply step into a chinese town and pacify everything.
-merging crossbow training into a complex is a bit of a stretch since it was more or less up to the engineers and intellectuals than soldiers to know how to make and use them. crossbows were made for ease of access to untrained solders, not just another way to bring missiles to the battlefield.
