Introducing snowboard-basketball

So you have heard of snowboarding. And basketball. But what about basketball AND snowboarding, together at last?! Here is a video that blew my mind recently -- snowboarders in a half-pipe, dunking snowballs into a bball net. Some were better than other, but the idea itself...why isn't this an Olympic sport? And would Lebron James or Kobe Bryant destroy everyone in this competition if they learned how to snowboard?
