Zombie Wandering Trader ghost

So the wandering trader usually despawns unless or when frequently killed by the player. So what if, the same way a wandering trader tries to spawn every day and sometimes succeeds, there is a zombie wandering trader that tries to spawn when you have killed one. So every time you kill one, it comes at night and slowly tries to come closer to you. It can come closer to you gradually and can open doors. If you look at it, it won't move. But, somehow if it goes unnoticed and comes like 2 to 3 blocks close to you it will start dealing damage until you kill it.

This could be there for only hard mode because of the intense jumpscare. It will also increase respect for the hard-working wandering trader.
