Possible, certainly. Fun, not so much.
Some weapons like bonk, machina, mad milk, vaccinator, etc need major reworks even after years of them being in the game (not that it was never attempted by Valve, but the many changes to vacc for example were insufficient every time).
Valve has at times taken 4+ years to balance some weapons that were insanely broken (anti-headshot danger shield). Others like the sun-on-a-stick have been useless for 8 years.
It's also been a long time since the last decent weapon balancing patch (though it did show somewhat competence from Valve's side, maybe only because they did what comp players told them to).
There's no way for us to know when or if ever some of the problematic weapons will be changed. And if it'll be for the better once it happens
Overall I'd say the weapons are in a somewhat balanced state compared to past years (anti headshot danger shield era for example it would've been an even bigger snorefest to have a koth map in RGL's no whitelist league), but simply because it's in a better state than before doesn't mean it's where it should be just yet
