I'd keep agility as the main attribute weapons but apply a minimum brawn prerequisite needed to operate the weapons without malus or being able to operate it at all.
Assuming most of the named item Qualities which aren't specific to the lore of a Galaxy Far Far Away carry over, I'd assign bows the Cumbersome Quality, which does more or less what you describe. Then leave heavy weapons with Brawn, but give them the Unwieldy quality, achieving an inverse of bows that roughly fits how weapons are used. And potentially the Prepare or Slow-Firing Qualities to crossbows, requiring a manuever to "reload" either before shooting or immediately after.
I might make bows and longbows deal damage like Brawn weapons (e.g. add your Brawn and successes to deal damage) or allow a player to spend 2 advantages to add Brawn rating to damage dealt with bows (Talent on a specialization tree).
