So, looking through options and realized - with a significant "oh, duh!" moment - that I should have more than enough unarmed civilian men already primed and ready for painting in my Three Musketeers collection.
Potentially 'problem' solved. And if not enough, I can probably dragoon in the most appropriate figures from my Robin Hood and Jousting set-ups; might not be a 'perfect' match but probably only need a relatively small number and there are likely enough generic figures to work.
Unless...I decide I want the figures painted a bit different. We shall see.
