No way. The descent rate is approx. 30 degrees. Even based on your own picture. The airfoil produces peak C_L at about 13-16 degrees. After stall it mushes, which is what happened in that video.
The chicken whisperers design is based on the Icarus V. It's a hang glider designed for 18 mph stall speeds, which makes it suitable for those takeoff conditions. I think I remembered seeing another team with a catapult powered with elastics?
