That could work. A nurse version of Arnold Schwarzenegger xD

My only caveat is that you might lack a little bit in the healing power department due to being limited by basic medical toolkits. But what about a Psyker who specializes in Biomancy, particularly the healing & flesh knitting part, or an Adept of the Mechanicus who specializes in human biology and anatomy?!
