Broken Monster Spawners

To expand the build pallet, I would suggest a slightly modified monster spawner. Instead of breaking the monster spawner and getting nothing, you would get a modified version that has a slightly damaged texture and it also does nothing; effectively making it cosmetic like the dragon egg. Making it just a decoration block would keep the game balance in order. An example of a decoration would be lobster cages in a fishing town or even full iron bar blocks.
