Depending on your application, there are hi-rise stems meant for hybrids and city bikes that might get your bars where you want them without taking chances on a mountain of spacers and an overstressed steerer tube.
I am 5'9" and using a 56 frame the bars are just over the height of the seat. I may have to rethink the front end on this build. I am using a merlin RSR frame that is 5 years old. I have been riding my hybrid for the last 12 years and thought I could ride just as high as that bike. I have seen some hi-rise stems and will look into it thanks
