Block that allows Piglins and Hoglins outside the Nether

My idea is for a block, named the Nether Seeder for the purposes of this post, which would allow Piglins and Hoglins to survive in the Overworld and End. My ideas for how the block would work are as follows:

• To craft the block, you'll need to put a dispenser in the middle of your crafting table grid, then surround it with eight pieces of crying obsidian.
• When you first craft it, the block will be inactive. Before it is useful, you'll have to place the block in the Nether and right-click on it with a dragon's breath bottle (this uses up the bottle, and is meant to show the seeder sampling the nether and turning it into a lingering effect).
• If placed in the Overworld or End, an active nether seeder protects all Piglins and Hoglins within a certain radius of it (probably 50 meters) from being zombified.

I think this would be a fun tool to have in the game for players who want to 'settle' Piglins in the Overworld or End, either just for the fun and challenge of it or to populate and enhance certain builds. I think the use of crying obsidian in the recipe is necessary since it requires a player to have already done a lot of Piglin bartering to get it, which means having Piglins in the Overworld probably won't make things too much easier. I think the use of Dragon's Breath to activate it is important because it ensures this is an endgame item. These things together will hopefully enable a fun and useful feature for players interested in it without upsetting game balance much if at all.
