I just released a new addon called Lineworks.
It gives you the ability to add stylized lines to your characters. The lines will inherit the motion of your character and have a rig to further refine your lines shape. You can create grease pencil lines or procedural mesh lines.
You can find an introductory video as well as a tutorial series on how the addon works here:
