Well, I suspect a udev rule *might* work to rename the discs, but labels
or uuid's aren’t designed to *change* the name (who cares?), they are
designed to cause mount to "mount" the expected disc :) It makes much more
sense to focus on that than to maintain aesthetics which again can be
changed in the future so the solution is not failsafe.
To each his own I guess!
