Now that you mention the possibility, it does bear a certain resemblance to one of the mechanisms in Regimental Chess (we have a link page but the link is broken; you're better off doing a web search and checking out some of the videos they made) exactly for this purpose.
The difference there (if I remember correctly) is that like pieces follow like, rather than always going in order of strength or allowing free choice. And it may or may not be optional there.
