Alloying and trims

We should be able to trim things like horse armor, elytras, nautlaus armor, and maybe weapons, and maybe metal alloys like Rose gold or green gold. It would work by putting something like a cauldron over a camp fire and throwing gold, copper, and iron or maybe netherite and it will melt after a few seconds. you can mix gold and copper, iron and gold, Copper and Iron etc. you can put it in a bucket and put it in a hopper or something and ingots will be produced. A blast furnace or A new block known as an ingot cast can be put under the hopper. The cast is a furnace variant and smelts like it. It will produce the ingot. It Could be used for trims or Armor and tools. This should make trims better in my opinion. It would Add more combinations and be an awesome addition to the armor catalog and make it more interactive.
