I had a very similar setup but about 6-8 ft shorter. It was alongside my garage and the wind did pick it one time and blow it about 20 to 30 feet away and bend it all up. I straightened the pipes out and put it back together, this time clamping the one side of it to the garage so it would not blow away again. An unexpected October snow fall flattened it down on my boat. I would not recommend your plan.
