Well, I would suggest to give it a try 
.
With the style of Stonehearth you will run into some limitations (if you want to stay true to it), e.g. the mouth is not shown on models and also the flexibility with eyes is a bit limited. You might need to use other things to increase the recognition value (like special cloth or items carried / used by the character).
P.S. You might like this thread for some impressions on how it could turn out.
