I have considered creating my own template by combining arms and legs most uncovered. I noticed that there's not just one template for all characters as there are slight differences in leg positions, etc. to help offer a more natural appearance. But it doesn't seem as if there are that many models so while it would take some time to do it, it wouldn't be terribly bad either.
You have good eyes.

Another way, if you want to mod the game's art would be to pixel-edit out the limbs (as in, erase the clothing and leave just the limbs) and use that as a masking template in Photoshop. it'll be tedious, but once you do it the first time, the mask will do the hard work for you for any other villagers with similar outfits. It might not be perfect, but it's a place to start.
