@odenskrigare,
I'm fleshing out the Chinese story more
First of all, I noticed that I'll have to break with strict Mohist doctrine since it forbids offensive war and is somewhat more authoritarian than the heroes of my story. (Up until now, I was mostly familiar with their logic, rather than political philosophy.
Mea culpa.)
The episode where Qin is destroyed should be a daydream by a student in the history class. At the end of it he drifts back into reality and listens to Lv Laoshi (Ms. Lv)'s conclusion about the reversed distinctions between Chinese and Western civilization.
The revolt leader will be male, but I want one meaningful female character, to give a good role model and be inclusive. I'm thinking of combining Hypatia and the Trung Sisters into one person: she'll be a logician of merit; I'll attribute aspects of modern logic not mentioned in Mohist writings to her, namely shifting away from analogical inference, which Mohists acknowledged as potentially unreliable, towards deductive, syllogistic ("three section discourse" in Chinese) reasoning. And she'll also stick an arrow in Meng Tian's gob just before he slashes the leader down.
The Sennacherib story should include Sennacherib (who will probably be given a mundane American-sounding adoptive name like Craig McLeod) commenting on US victory in the Middle East with something like: "We cut their throats like lambs", recalling Sennacherib's inscription celebrating his victory over Elam.
