Now, here's a question: what sort of head angle would you aim for in a 69er or 659er? Starting position on the goose is 71 degrees for 26ER. Changing front to 700c will make the angle slacker; changing rear to 650B will tighten it up. My rigid Bxt is 430 axle-to-crown. Looking at chinacarbon forks, anything between 380 and 460 is possible, which will allow to dial in a couple degrees of final angle, if I was to use a different fork.
