I honestly couldn't care less about positionals anymore as I feel like they are indeed an outdated battle system, especially with those planet-sized hitboxes and auto-centering bosses.

Now I played monk as my preferred Melee back in ARR and it worked well before but I much prefer the focus on their combo optimization like your freedom during perfect balance. If anything, a heavier focus on combo strings would make up for the positionals imo.

As for the other jobs, you could consolidate redundant buttons that only exist to hit positionals for a new button that contributes to the job identity, that's what this game lacks in their jobs the most
