Why it's not gonna work
What Disney has done is to take the Mulan story and to wrap it with the wuxia style. Chinese cinema didn't even do that (and they created the wuxia style).
Wuxia is the movie genre about epic ancient China where warriors have super-human skills. Crouching Tiger, Hidden Dragon is a known example. In Wuxia movies female warriors are quite common. However, those movies don't try to be realistic (people often chase each other jumping from tree to tree and from roof to roof across the streets) and what's more important, they're cohesive: in that universe females can make lethal warriors, people know it and act accordingly.
Mulan, on the other side, it's a mythical but half-realistic story about a woman in an ancient China where females don't fight and they don't make lethal warriors. In the Chinese versions, Mulan is not portrayed as a 'powerful warrior' but as a very clever girl that is willing to sacrifice herself to protect his family but ultimately becomes successful thanks to her intelligence, leading skills and courage.
Why is it a bad idea to mix Wuxia with the Mulan myth? They're different universes with different rules. If you take the almost super-natural female warriors from Wuxia movies and place it in a Mulan universe where female don't make lethal warriors... what you'll have is another serving of woke propaganda, with the 'stupid males' saying that females can't fight while Mulan is fighting as she was the ultimate warrior in front of them.
You can or can't have female lethal warriors in your movie, but you need the rest of the narrative universe to be cohesive with your choice. Otherwise, what you have is propaganda.
