I have two armatures. One is a character model that has a rigify armature on it. The other is a jacket that has standard bones.
The jacket's spine bone's names are different from the character's ORG bone names, but nearly have the same location, rotation and scale.
The character armature contains extra bones that aren't rigify.
For reference, here are the jacket's bones

What I want, is to merge the jacket's armature into the character's, remove any bones from the jacket's armature that have a similar counterpart in the charater's armature, and keep any extra bones from the jacket. Finally, the jacket should be influenced by the rigify armature.
How should I do that?
