I'm preparing thecubber's dwarf from Opengameart for OD now. I've already joined all the different parts, combined the textures into one (baking worked surprisingly well) and tested him in-game. He looks good, but the basic test animations that I made didn't work, probably because the model has two armatures. I'm not sure if there's a way to export them both.
Also, the normal map has lost some sharpness during the baking process and I'll have to see if I can get a better result or increase the intensity of the nor map in PS.
