Unique feature and items removed from Minecraft

Thier used to be a bug were skeleton horses could drop armor with double enchantments making really cool items like a prot 6 helmet and prot 6 bow. These items were extremely rare around 1/11million. It was very niesh and retroactivly was taken out in 24w11a. The helmets were comprised of dual prot 3 and one of a kind. I’ve been holding out updating my main Minecraft world and loosing my rare items. It would be cool is somehow they could transfer over. Like instead of removing one it would add the 2 prot 3s
