In some scenarios (e.g. in my case I'm using Hardcore Torches and Unlit Campfires, but the regular items generate in the world) it would be ideal to have an option to set certain items to be replaced by one of our choosing instead of blacklisting them entirely.

Example 1: I could set minecraft:torch to be replaced by hardcore_torches:lit_torch, so that if I break a torch in a structure it would drop as the modded version, and torches generated inside dungeon chests become their modded alternative.

Example 2: a mob in a mod drops a item I'd want to blacklist, but blacklisting it means it would give no reward, so I could replace it with another item as reward.
