I don't see this as a valid analogy. You can't aggregate the dull knives in order to almost replicate or even improve the cutting performance of a sharp one.
But you can use many separate mirrors with artifacts to replicate a perfect mirror, as long as you are able to do some post-processing on the array of mirrors with artifacts. And with proper post-processing you may even be capable of extracting additional information which a single perfect mirror would not be able to deliver.
