Should work just fine. In this case I think one is designing to a yield and not a stiffness anyway. The diameters mentioned on Walt Dimick's home page are designed using proven diameter rods, Harley has shown that, Walt is just providing them a little harder. Your suggestion of using a larger diameter steel tube in theory is fine, but you still gotta find room for it. A simple hardened steel rod with adequate stiffness and strength follows the KISS principle to a T.
