The jump biathlon.
Picture it: A guy is standing at the top of the ski-jump ramp with a rifle held at port arms. The signal is given and he shoots off down the incline, carefully shifting the rifle into a more useful position while holding a tight tuck. As he shoots off the lip of the ramp, he leans forward with the butt of the rifle against his shoulder and starts blasting away at a series of targets set just to either side of the center of the landing slope. These would be large and very orange to make it fair, and to make it even more fair these would be automatic rifles, perhaps Kalashnikovs.
This would be a beautiful thing to behold and a huge TV draw.
