The easiest solution is to avoid mirror:// and pass a list of regular
URLs:

  (origin
    (method url-fetch)
    (uri (list URL1 URL2 URL3))
    (base32 …))

See for example how ‘qtbase’ does it.

Now, if you really want to extend the set of things recognized, you
could write variant of ‘url-fetch’ that passes a different #:mirrors
argument to ‘built-in-download’.  Maybe ‘url-fetch’ could have a
#:mirrors parameter to simplify it.

But really, the URL list should do the job most of the time.
