@craptakularuk I did exactly that to start with, long monster desk mount, and it works.... sooort of. The long mount can certainly handle the Rhino, but I wouldn't call the margins comfortable exactly. There's a fair bit of flex going on, and I worry about the long term stress on the desk edge, unless your desk is solid and strong hard wood. I'm putting together a better (I think... hope) solution of my own, but it remains to be seen if it will be effective, and there are others here who have designed and 3D printed their own mounts to solve this problem. Worth a search! No S-curve extension for me, using Winwing Orion 2 and its 100-200mm adjustable straight extension and monstertech chair w/center cutout.
