Wither Piglins

My idea is that when a piglin or a brute piglin dies from the wither effect they transform into a wither version of them, let me explain, when they become wither piglins they will continue having their golden sword (or the last weapon they had) and attack evergy creature they found (not including wither skeletons, skeletons, blazes, or other wither piglins) and when they it you or any mob they give the wither effect and if you kill them they could leave you their clothes, the clothes will make you more resistance to the wither effect but it will make that the healing potions heal you the 25% (or the porcent that you want) of the hearts, i would be grateful if this idea gets in the game but if you don't want to added it i'm ok of that thanks for reading :)
