As for the inverted UNO, you might consider adding a reset button since the Uno's will be obscured, or remove the board underneath it so one can press it. Being inverted, it should be at the lower left corner, no? I guess that would depend on the final orientation.
Regarding the board I posted, I checked dirty pcbs and they have a blanket cost for 10 boards, 10 x 10 cm, for $25-28 USD, so that's less than $3 per board.
Pot's compatible with the ones I used are $5.59 USD shipped within the US for 16 on eBay, so about $0.35 each. The biggest differences are these have a shorter shaft, and have a center detent. There's a listing for 1,800 of these for $70 USD too.
I'm not sure about the screw terminals yet, but probably a less than few dollars each ignoring shipping.
LED's, resistors, switch and pin headers should be less than $10 USD all together if sourced from eBay or similar.
If someone made a batch of boards, it looks to be about $30 USD for everything less shipping and the Arduino.
If there's sufficient interest, I might have a go at this.
Or if anyone has suggestions for changes let me know too.

I'm going to cater for the home DIY toner transfer crowd and try to put the UNO upside down on the top if I can - soldering will be easier -.I understand completely the DIY thing.
