How can I do this automatically? Something like:
1. Select all bones to be "fixed"
2. Run an operation
So far, I'm stuck doing this manually, by placing the 3D cursor at each bone's head, deleting the bone, extruding a new one from its parent, placing the new bone's head where the 3D cursor is, and renaming it. This is pretty slow and cumbersome.
I can't benefit from Merge Bones (Within Chains), since it doesn't do anything (presumably because the bones are disconnected and not a proper chain). I've tried selecting two bones, two tails, two heads, or one tail + one head; all no luck.
