Simple bone single skin is not optimal for a Poser figure. It basically just converts the rig to be exported to other apps. You get one weight map for each body part and you're essentially back to the rigging used in Poser 1, just with a weight map instead of a falloff zone. That means you're using JCMs for each and every joint rotation unless you like that bent straw look on shoulders and elbows. 

This isn't a bad option for mechanical type figures that don't have fleshy stretchy bits, but otherwise, it's a big nope.

I've experimented with numerous 3rd party figures that tried to reinvent the wheel when it comes to rigging. Some were much more interesting than others but ultimately all of them failed because most users weren't interested or found them too complicated to work with.
