It could be revelatory.
Like the first time I played Super Mario Bros. on an LED screen. Finally I could see each pixel clearly, exactly the way the original artist didn't intend!
Edit: in all seriousness, this makes me wonder: has anyone ever re-orchestrated Beethoven's Fifth? Say, in the orchestration style of Ravel or Strauss? Someone must have done this, even as a joke, and I'd love to hear it. (I know about the "Fifth of Beethoven" disco tune which is great, but that's not what I'm asking about.)
