A bit of progress. I’ve started a sculpting streak and so modified/converted the 7 Perry minis (6 from the robed Samurai pack and 1 from the Armed Peasants):

Gorobei uses the bow and quiver from an Ashigura Archer (thanks James), Schichiroji is lacking a spear but the pose doesn’t suit one, while Kikuchiyo’s sword is from a plastic pole weapon (it does have a curve, it’s just not visible at this angle).
I’ve also settled on a village layout for my 5x3 table (white splotches are trees, Green are hills):

If (when) I get a bigger table, the village will be easily extended.
