I have found the space western theme (aka Firefly/Serenity) works pretty well in 2300, MT HT and TNE.
Part of me was annoyed by Firefly, I thought the emphasis on elements from the Old West and attempts at revisionist history of the American Civil War were over the top ( 'Firefly' the lost episodes: Mal berates an Alliance officer for taking away his freedom to own slaves, Cobb goes on night rides with his buddies to remind those sub-humans what is their place *) but I still see the Firefly universe as the basis of my view of what the Chinese Arm looks like. Especially if you read pg 131 of 2320AD and particularily if you read the paragraph at the bottom on the left column. Just switch the names of the the fascist Alliance with the fascist Manchu's including misplaced idealism and petty corruption, give the Reavers a Provolution origin **, replace the Unification War with the CAW*** , give the crew of the Serenity a Texan origin which they pretty much have anyways and POOF! ...you have the Chinese Arm with all of it's chaotic clash of cultures including aliens but an oriental underlay, small&isolated colonies, long distances and distant but totalitarian government.
*Actually not all that unreasonable that some human outposts in the Chinese Arm might have some Xiang slaves. I am not saying that they ever entered public, or common, service but small, isolated farming and mining operations always have labor shortages and after the Slaver War certain Sung families would be seeking to dump their now illicit workers at a cheap price ... sounds like a good basis for a trade.
** or not. I have to think that the relatively large presence of Provolution on the Chinese Arm is because they enjoy a larger degree of public sympathy than other places. Perhaps the only difference between the Manchu government and Provolution on the issue of cyber/bio tech is that while Provolution dreams of being supermen the Manchu government dream of legions of loyal supermen. So the Reavers could still be a berserk government research project but now associated with Provolution. If you really wanted to play against type you could have the players be the 'good' Provolution operatives who set the Reavers free from the evil government bondage ....

Etranger write-up on the Tunghu for an unconventional response to rampaging conventional French forces. Perhaps the post-CAW French peacekeeping forces could take the role of the evil Alliance, enforcing a liberation of a people from their independence.
