This would mean that you can mass reinforce pre-waxed copper without having to manually un-wax them all. This isn't a duplicate this way, as no new copper reinforced blocks would be necessary.
Obviously, doing it this way would by necessity be at a huge loss to the player who would lose their spent honeycomb if they ever decided to unreinforce their blocks. But at the same time they gain back a lot of otherwise wasted time unwaxing.
The only problem I foresee is reinforcing them by mistake.
