Have to confess, symmetry painting is not something that concerns me much. Useful for generating repeating patterns in some instances, otherwise more an artists tool.
You can use the symmetry painting tool on different layers, the only limitation that I can see is the layer has to be the same size as the canvas. Moving the guides is a bit of a pain, the symmetry painting dialogue is used.
I think you will have to submit that as a wish to the developers - same bugzilla as I referred you to before. I suppose the clue is in the name - symmetry painting
While you would need to use the 'flip' tool to replicate paths, you can still stroke the path using the paint brush option.
