Add More Height

Has anyone added more height to the AO 101 printer? I was thinking today, first problem, that it would be an easy task of just adding longer angle 20/20 and longer guide/threaded rod. If you just supported the threaded rod at the top so it still spun but not be able to move side to side I think it would be ok. Possibly have a thicker rod but I would think that would be it. What, if anyone is still here on this old thread, do you think?
