darkestdungeon Mod Question

[sirlogan997]

I'm new to all of this, but would it be possible for someone to make a mod that changes the aesthetic of weapons so that they match what level of weapon a hero has? For instance the crusader having the crappy battered longsword as the weapon his character model uses at the beginning, but then at the last level him actually wielding the Long Crusade? Sorry if this is a stupid question, I'm just curious.
