Is there a mecanim armature/skeleton that can be imported into 3d progs like Blender?

I am about to do the third iteration of my base humanoid. And I was thinking, it would be nice, if I could just import a skeleton that is "optimized" for Mecanim, just meaning it has all the bones Mecanim expects for a full character, and names them all the way Mecanim does. I understand most of this is pedantic, but if I am making a skeleton, specifically for Blender to Unity, I might as well shadow everything that Unity does as best I can. Because who knows what they do in the future, or how?

 

Not that I'm aware of, but you could generate one from the stuff in the HumanTrait class. https://docs.unity3d.com/ScriptReference/HumanTrait.html

 

I think this will work:

Although I am sure the principles in the set up instructions will still work fine.
