Interesting idea, Bill.  The origin of quoining, as I understand it, is that squared stones were structurally important at the corners and over openings, whereas rough field stones were acceptable in the body of the wall, especially when said wall was to be plastered. So people would leave the pricey dressed stones exposed. 

My first thought was using AAC blocks for the corner, but they're so brittle, a small column of them seems too delicate. And  I wouldn't leave them unplastered. 

Maybe just a veneer of something tougher than plaster over the bale corners?
