i didnt watch the videos but im sure this is what you are wanting kind of. this is what inspired me to look for human class overlays a few weeks back ;) unfortunately this addon does not work ever since the update, ES_Tools got borked. =(
anyways if anyone knows how to code this into a .smx plugin that would be sweet!
