Sounds compact and very adjustable. I can imagine how the ability to rotate would make it more versatile than the windtech. Looking forward to seeing pics.

nano > reversible stud
nano > reversible stud > rapid adaptor
nano > reversible stud > rapid adaptor > rycote inv-6 shockmount
Note, the rapid adaptor terminates in a 3/8th-16 screw if you want a size reference for the entire package. (assuming you don't have a rapid adaptor handy to compare). The shockmount is oriented in such a way that the weight of the kwonbar/mics/cables/etc will cause it to torque
into the threads instead of unscrewing itself (very important).
Between the rapid adaptor, which allows me to go out (as shown), up, and down, I can rotate the adaptor in any of the three configurations (and level up or rotate the shockmount) if the pole I'm clamping to is at an angle instead of straight across or straight up. Last, I can rotate the shockmount itself around almost 180 degrees so if I need to clamp and run off the side (say, slightly off center due to environment restrictions on where to put the stand), I can try and correct for some of that. Really a versatile setup in that regard. Your point of failure would likely be either be the friction of the rapid adaptor's press hold on the stud or the nano clamp's max weight (which isn't much, but easily enough for an active/remote capsule setup after accounting for load). I've never had problems with this setup though.
The only way I know of to get a smaller setup would be to buy a nano, a small bit of 3/8th threaded rod, 3/8th > 5/8th adaptor, and a shure donut screw. Then get everything just about screwed in and apply super glue or loctite and let it settle in the desired position. That would be even more low-profile clamping setup than anything else I could think of but at that point you're almost/probably just stealthing and wouldn't be clamping anyway.
Speaking of, I almost took the last picture with a shure donut (which is smaller than my inv-6) but I didn't want to hunt for it.
