Original Destiny 2 Redeem Code

[Bearishion]

Does anyone know what would happen (or if a mod or someone who works at Bungie be able to tell me) if I redeemed an original Destiny 2 redeem code for Blizzard? I still have an un-redeemed code for the game itself (tested the code and Blizzard still recognizes the game code) and the code for the Coldheart that expired in 2019

Probably nothing since it's not on B-net anymore.
