Archaelogy Idea Mojang should add

An Idea for achaelogy rewards. When you find an excavation site theres a chance of finding pieces of crafting recipes for things you can,t currently craft If you find all 5 pieces you have to work out how to put them together as a puzzle when you figure out how to put the crafting recipe together you can put it into your crafting table and craft whatever the recipe for it is. So for example horse armor is currently uncraftable but if you dig up and spend time digging up  all 5 pieces of the recipe for horse armor and then have the fun experience of putting it together as a reward  you can craft the uncraftable item. I think it would be super fun as a puzzle to put the pieces of recipes together to make one and being rewarded with being able to craft something you can,t currently craft like tridents or totems or horse armor!
