With that crank, I'd give it a try with the existing 9-speed stuff.

Though, I'd rather sell the overpriced Dura Ace crank and stay with the 2x9 setup.

May be a silly idea, but my first thought was to use the RD adjustment screw and limit the RD movement to the 15T rear sprocket. If it will go that far (the limit screw).
