Chuck,
Why not invert the scope on the Gerrish mount and put the mirror on the high end. That way you can use any focal length and make the whole thing somewhat height adjustable. I don't think the photons have a particular aversion to traveling down instead of up, although CERN may change that any day now.
Hi Brent, good to hear from you! I'm honestly not seeing much practical advantage to inverting it other than swapability, the stand would assume petty tall proportions even with a short-focus scope. Keeping it pointing down is the most compact arrangement. It should work fine with the f/5 doublet.
