Had a look, sadly there's nothing close for the Captain (who's easily the most important one to find). Captain Josiah is a short and very stocky fellow, with a different sort of face, big heavy boots and a deeply ribbed shirt. Artizan's few merchantmen all have a German flavour to them and wear buttoned-up coats.
I was actually amazed that Bob Murch didn't have anything close, given he has more than a half-dozen merchant seamen packs.
I actually spent a bit of time going down the full manufacturer list. It might come to having to do a couple conversions.
