For a long time, I've been trying to find a figure I could convert into Chang for a Tintin League.

What I need is something of a tall order: A Chinese or Asian civilian in the right scale, in rather plain dress, who is smaller than Tintin but not by more than a couple of mm. For reference the Tintin figure every (myself included) is the Copplestone one which is 29mm to the top of his head (30mm, if you include his famous hair tuft).
I don't mind figures of different sizes and heights, but proportionality forces me to be picky in certain cases. Just as the Captain had to be taller than Tintin, so does Chang need to be shorter, or at least not higher than 29mm.
I've thought about some of the Copplestone Chinese, but they're actually larger and bulkier than Tintin by a very noticeable amount. Obelisk's Boxer Chinese civilian line (now discontinued anyway) were mostly in dressed rather obviously in the more elaborate 19th century clothes and most of the men in that line were plump shopkeepers anyway. I've looked at the 1/72 Red Box Chinese boxers (thinking I might go one scale down) and they seen terribly cheap-looking and also in pretty much unsuitable and ridiculous combat poses. The IHMN Tongs don't seem like they would work either. Tsuba's Japanese would actually be a perfect size with the right type of face, but they're all in very heavy kit and conversion would be a nightmare.
Foundry doesn't seen to have any boxer civilians. Does anyone know if they ever did in the past? I know it's a long shot, but maybe there's an OOP figure I could use.
I don't expect to find exactly what I'm looking for and I can convert within reason. Is there anything even remotely close to what I'm looking for?
