I've seen a few house mods which would alter weapons. An example of something I used changed the maul from 9 normal dmg to 3 ap damage. The balance of course is that while it's more effective against heavily armored opponents, it's far weaker against unarmored ones (This may not be desired by some people).

Is that what you hand in mind? And if so, are you suggesting that to be implemented in the vanilla game?

If not, then a mod which changed every blunt weapon would be a rather straightforward and simple affair to make for yourself.
