Yes, to 'reverse' shaping, all you have to do is put it on the other edge. The L front has you dec/inc at the beginning of the row, so for the R front, do it at the end of the row. You can't BO at the end of a row, so you do that at the beg of a WS row instead. The decs can all be done on RS rows though, just at the end instead of the beg of them.
