Ore Rocks

Because of the new grimstone update, there will be multiple types of ore blocks that will take up more inventory space than desired. Ore rocks could be added as a measure to fix this. I'll use gold as an example. Once gold is mined in the nether, in stone, or in grimstone level it will drop gold ore rock, having the texture of the stone, netherack or grimstone missing and only being gold, allowing for the items to stack together and take up less inventory space.
