Actually if you subject the metamorphic rocks to sufficient erosion, they become sedimentary by definition. Metamorphism is just the compression of other rock under heat and pressure, and not any fancy transformation. Though I think the rock analogy here is pretty farfetch'd to begin with, just serve your rock soup with leeks and call it a day.
