Ever since 1.4, you have been able to obtain items from the other evil biome once in Hardmode through the Dryad, including everything unlocked at that stage of progression. But there is still one item that can't be obtained outside of the drunk seed, being one of the evil biome chest weapons, Scourge of the Corruptor or Vampires Knives. Allowing you to shimmer between these two items is a simple solution that wouldn't require adding anything new, like biome lockboxes or something similar would require.
Also maybe you should be able shimmer biome chests back into biome keys, since for some reason that is a one way conversion, not that it would be game-changing or anything.
