Goats Eat Enchanted Books

Allow goats to eat enchanted books thrown onto the ground. When a goat then loses their horn, it will have whatever enchantments the goat has eaten. When the horn is blown, those enchantments will temporarily be added to the player and their mounts. For example, horses would now be able to use frost walker. Maybe new enchantments could be added to temporarily exist, maybe because they would be too overpowered otherwise. New depth could be added to PVP this way. Not only would your choice of gear matter, but also the enchantments on your horn. Making horns usable only when not holding a shield could give the players a new choice to make while in combat. Remain protected by the shield, or activate their horn buffs?
