Pressure Plates (bumpers) on walls for Sulfur Cubes to interact with

So it's like a button, but instead of pressing it, you hit a Sulfur Cube (any mob would work, but Sulfur Cubes work best) into it and it takes up a full block. And, like regular Pressure Plates, it ha a gold light weighted and iron heavy weighted variant with gold being a weak hit, and iron being a strong hit. There could be a lot of neat minigames and even traps.
