Good points and thank you. History is hard to kill--although my colleagues take a run at it.
If you know any suitably conservative economics professors, I'd suggest an addition to your curriculum on the evolution of economic theories and their impact on history over the past 500 years.
Most history courses ignore the economic theories that historical powers used as the basis of their decisions, or they cover them in discrete units without any coverage of the evolutions, transitions, and conflicts between competing economic theories and their contemporary and counterpart political theories.
You might even be able to write a supplemental text book on the subject.
