The easiest thing to do is get a set of 8 speed downtube shifters and run them as 9 speed with the rear derailleur cable in the alternate position. You would be able to run all 9 speeds because there's an extra click on the 8s shifters.
I've also heard that Dura Ace 7700 bar end shifters can be removed from their pods and mounted to down tube shifter bosses. Maybe someone here can verify this. I do know that Gevenalle Audax cyclocross brake levers (with square down tube bosses mounted on top) can be run this way with either bar end shifters or down tube shifters for a super durable fun alternative to brifters. I have 3 x7 Shimano 105 SC down tube shift levers mounted on these Gevenalle (company used to be called "Retroshift") brake lever shifter pods.
