Tom;
That's called "Guilding the Lilly" by the English, sometimes inaccurately called "overestoring", inaccurate because it's actually customizing not restoring. If you have a spare chassis or get a radio where the cabinet is more or less destroyed then there is no harm in building a custom cabinet in any shape with any veneers you like. But I have a bit of a hangup about such things being done with a cabinet that is easily restored to the way it left the factory, someone will end up with the radio down the road and may think it was a deluxe cabinet of limited production.
I see this on that "American Restoration" show all the time, like chrome plating parts that were painted, or polishing aluminum to a mirror finish when it had a matte one to start with. Although it may look pretty, when it comes to cars and motorcycles it actually reduces the value both historically and monetarily.
