It's not like the monk's fists are bigger or sharper than anyone else's, they just use them better. HP, Armor, Damage, etc are all abstractions anyways.I can’t remember which game, but there is one where you just do your class’ HD in damage regardless of weapon choice. So a wizard can wield a sword, but it does 1d6 damage, while a paladin using it does 1d10. Pretty simple.
At least until a player figures out a dagger does the same damage as the sword, but is easier to hide and can be thrown. But you could apply some generalized modifiers to balance weapons. -1 if throwable, -1 if small, +2 if two-handed etc.
