If your going to change the rear to a 5 lug patter, i'd change housings. I hear people say that some axles are interchangalbe perfectly, but i've found that all the 5 lug axles are longer than 6 lug axles. The results is your drum doesn't line up with the shoes right plus, the outter axle bearing won't ride on the machined part of the axle.
