Aging In Structures

With 1.17 and 1.18, we've been introduced to copper and the aging mechanic, which basically oxidizes the copper the longer it's been in the world. With this new mechanic, however, I believe it could be added into existing features, mainly Bastions, Nether Fortresses, and Strongholds. My idea is this: when you spawn in the world, a timer begins, ticking up for every second you've been in the world. The timer gradually increases, and as it hits certain points, the previously stated structures will erode. This will not destroy blocks, but instead will change them from their normal variants(blackstone bricks, nether brick and stone brick) into their damaged variants(the cracked versions of the before mentioned blocks). This would add another level of impressiveness into the Minecraft world, and I honestly believe it would be an interesting mechanic that would be fun to see how it plays out.
