Yes! Bones are a great base for adding more strokes and duplicate shape groups and all kinds of amazing stuff if you just know how to use shape layers. Twirl down the layer, then Contents and then Limb and you'll see Limber's Path and Stroke. You can add more strokes by selecting the stroke and clicking Cmd/Ctrl-D to duplicate it. A more flexible method is to duplicate the entire Limb shape group (rather than just the stroke). Then you can, for example, use Trim Paths with some strokes and not others, and build up several different strokes with different widths, colors, tapers and cap types.
