Usopp isn't Luffy. He doesn't magically gain new powers. I always fail to see people's innate need to overpower and ruin characters. While the poneglyph idea is plausible, your idea is not. Elizabello's punch didn't work because the walls are high grade steel over dense bedrock, which is next to impossible to break if you come at it horizontally, as Elizabello did.
