Safety is the one reason that anything like this is unlikely in a FIRST competition. While the actual competition environment can be controlled to mitigate risks, team labs cannot. My senior design project in college was a completely custom designed quadrotor back before they were popular and commercialized. Despite our tightly controlled testing environment including being tethered both vertically and horizontally, I very nearly took off the tip of one of my fingers. Those blades spin FAST. My finger got caught in one and the blade sliced through my skin and fingernail like it was paper. Thankfully it healed well without any ill effects, but imagine an out of control quad going right for any part of your body...
