Ore Golems Mod

Ok, so what if there were randomly spawned dungeons, themed upon an ore, and there was a giant ore golem boss fight. This mob would drop a stack of said ore. For example, you accidentally fall into a large room made of stone brick and diamond. You turn your head to see an enormous diamond golem charging at you to cool boss fight music! You manage to slay this golem, it falls to the ground and a stack of diamond explodes all over the room as it crashes to the floor! This mod would definitely spice up Minecraft. You, an unsuspecting miner, fall into a dungeon and get ambushed by a colossal rock monster, increasingly difficult to beat depending on the ore.
