Dave,
An option that I intend to look into at some stage or other is on-demand 3D-printing of figures that one has sculpted oneself in one's computer – a chap over on the Swedish modeller's forum on which I'm also active did this with some very interesting results a few years ago: **LINK**
Obviously the text of the thread is in Swedish, but I think already the photos speak almost for themselves.
Anyway, among other things he says that he used 3D-sculpting software called Mudbox, and had the resulting file printed by a online company called Sculpteo. The metal print-out he went for was quite expensive (and, at 1:16, would probably be a tad on the heavy side to put on top of a model boat), but at least according to what he says, plastic was also an option at a much more reasonable price …
As I said initially, this is something that I plan to explore, but have not yet looked into. I am, however, very attracted by the fact that it would make it possible to have basically any figure in any pose created to any scale.
Oh, and speaking of rivet-counting, I did of course take the chap in question to task for having put Frenchie's weskit buttons on the wrong side … 
Mattias
