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.
