@pooper Although the bone minion figure can be visibly intrusive, it can also be visibly eliminated in Preferences>Display>Show Bones>OFF. I just tested it out, and it works perfectly. I, too, was annoyed by it obstructing my view. But the value of the conversions faaaar outweighs the annoyance.
The results, although not literally perfect (given the figure differences), are so damn close as to be insignificant. Give it a try. You'll be glad.
However, I'm not sure if any of the Bone Minion batch converters available will do what you need.
