I hope to see and ride this design sometime in the future. You have a genius concept here and have lots of potential with it. I am sure this will launch into a full-sized coaster somewhere on this planet. You should be proud that you came up with this design when nobody else could.
Also this smaller and less expensive design could last longer due to less parts. More parts taking all this g-force could make it decay to fatigue faster. Since your design has less parts, it could last longer for continuous use.
I loved that hint you said in your video. Instead of bankrupting your company. Kudos to Arrow!
