possible but......
what would happen once your blew up all the rocks. we would be fighting in mid air but you can walk on clear floors. i think their should be a 5 foot (to scale) layer of ground you can destroy people can fall and put dents into. it should have rates of damage. 2-3 feet if someone falls on it. 4-5 feet from blast. make it even deeper like 10-12 feet and raise the scale.
you can send a kamehameha into a mountain and watch it crumble. like shooting the bottem would cause the peak to disentegrate. leaving a pile of rocks to hide, or you can destroy into smaller pieces and so on.
