I agree in an uncontrolled pitch up due either to cargo shift like a DC8 out of Miami about 20 years ago or runaway trim rolling into a steep bank is probably the only way to not stall. You can't reduce throttle because then you will stall anyway. Reducing flaps makes it worse so go full if that helps. Going around in circles trying to fix the situation isn't much fun but that is probably your only choice to have time to sort things out. That has always been my plan.
