Personally, I wonder if the way to make this situation more satisfying is NOT changing the weapon rules, and INSTEAD changing the fighter class.
Even more basic. Change the combat rules.
Take all those juicy special maneuvers in the feats section and make them combat options.
Then make the fighter the best at doing them.
Then figure out weapons; either make them full on abstract, or give them interesting properties, preferably ones that can be interpreted in either "realistic" or "wahoo" fashion.
It's a big ask, but do-able.
