This is a neat idea Congratulations.Yes it is ,the under seat frame is 1/2" OD and I am using 1/2" OD for the support rods clamping them together with 1/2" wire rope clamps approx 3" behind the main frame. So far this has proved to be a very solid connection, alternatively you could be more creative and extend the supports to the top shock mount as Denray does with their hitches.
Is clearance against the rear tire an issue?I built it with plans to pull a small trailer but came across the pakit rak and rivco cargo racks in my research and thought I would try that idea as well, I have a 28 qt cooler or 2 waterproof bags that fit on the rack depending on my needs.I liked the idea of an adaptable receiver type hitch as done by Joe Wolfe as opposed to a fixed type hitch as done by Denray.
