why not use one of these: http://www.brushymountainbeefarm.com/Plastic-Nuc-Feeder/productinfo/N423/
I used their wooden version for years before they discontinued it. I think I still have it in the basement somewhere. Not sure.
Of course I'm not set on boardman entrance feeders anyway. Never was a fan. It all comes down to what your mentor showed you and liked. Most people get hooked on equipment that way.
Anyway, if you are set on cutting up your nuc boxes and modifying them, your roundtable way of doing it will work just fine. The bees shouldn't be able to smell the old queen in there. Even if they do, the smell of their queen will over power the smell within a few hours.
