In theory, I could. I have no plans to, however.
Mustadio got that Tweak-inspired buff because he had some design issues in comparison to other special characters. The obvious comparison is to Agrias, who joins in literally the next story battle. Agrias can go from Holy Knight directly into Knight and immediately start working on Equip Sword, allowing her to take her base skillset everywhere she goes. And Equip Sword isn't super necessary: Holy Knight, Knight, Geomancer, and Dark Knight can equip swords just fine without it. These jobs give Agrias a massive number of build options if she chooses to invest in them. Maybe she won't be rocking Dual Wield & Blade Grasp if she sticks to them, but she can go Vehemence, Attack Boost, and Move +1.
Every other special character is like this - or better. Rafa and Malak, WotL Luso, and TLW Ashley all have issues in the versions they're originally from, and Meliadoul couldn't hit monsters in the PSX versions, but after their skillsets were reworked, they're all right about where I want them to be for when they appear during the game. But Mustadio's issue wasn't that he suffers from bad or gimmicky abilities. His abilities are pretty fucking solid! They just serve as an anchor around his legs if you have any intent of actually moving up the job tree, so you have to either ditch them for ages or just keep him locked in to Chemist and Engineer all game.
Mustadio has to go all the way to Mediator if he wants Equip Gun. While Snipe doesn't actually require any specific weapon, melee-range Arm Aim or Leg Aim isn't particularly great, especially if he's facing off against a target that doesn't have good compatibility with him. Those abilities are absolutely balanced around having an 8 panel range. Bows and Crossbows can make up for some of that, but it's still a downgrade so massive it would be like if Agrias started with a Knight Sword and only her base job could use it. I'm sure some folks out there have gone Archer Mustadio, but for the most part, I think everyone either leaves him in the base jobs or makes a beeline for Mediator. And what does he get out of that? Does anyone actually turn him into a mage? Probably not.
Bard and Dancer work differently than that, being intentionally deeply locked behind generic job progression. And while there could be some use to bringing their equipment out into other jobs, there are better equipment abilities on both sides of the aisle that are unlocked well before that point. Why use a harp when you could use a pole or a gun? Why use a cloth when you could use a spear or a katana?
Also, the way the hack accomplishes this feat is by making Snipe automatically activate the Equip Gun support ability. I am completely out of support abilities at this point, so there isn't anything left to bind those weapon types to.
