Sombre,

Balance rarely leads to more variety when the items in question are unconventional to begin with. More often, it is easier to bring those elements inline with the rest of the game. In the end you end up with scissors, rocks and paper as you suggest, leaving out fire, dynamite, water balloon, the attacking jesus and a toothless grin. Ultimately, it becomes a choice of left handed or right handed scissors, blue construction paper or college rule, sandstone or granite. They are different, but they are still rocks, scissors and paper, so there is no depth beyond learning the initial strategy, and there is limited replay value.
