My preferred configuration is the SE-14R + Hero. FWIW, this really only counts for getting your EI or Centurion. How you troop is up to you and the person running the event, so no reason why you couldn't troop with an ANH Stunt and an SE-14R.
Heck, look at TIE Pilots. No screen used reference for any of them wearing a side arm, but they sure do like to do so when trooping.
