Very cool solution, Patrick. I later read your comment about ordering a 13 first position and a 30/31/32 single big ring. Maybe that is what Steve P did on his franken-cassette. Sounds like an ideal solution for my CX bike w 46/34 up front and lots of hills I have to ride because I live at the top of one of the bigger ones around!
