Laughingleader ... I'm sure someone will Mod it in.
I've been thinking about modding that myself, mainly because I like the look of staffs, and making a physical monk-type of guy who uses physical staffs to fight sounds cool.
Now if these could be made and added into the loot table, I think that'd make Staff + Warfare a truly valid option. Yes, you won't compare to a guy who is rocking the 6-7 Physical Damage weapon, but it could make the Staff a far more interesting and useful weapon.
I could even add a new ability to those special staffs (or all staffs I suppose, if requested) - one that does physical damage, so you could have the option of using the default staff ability to shoot at range, or smack someone close to you for physical damage.
I'm actually working on a mod that does the opposite - It adds skills that scale with your weapon damage / primary stat, but they do magic damage. So basically a magic knight. I'm thinking of adding a basic ability like All-In that will do magic damage, so you have something to use as a replacer for a basic attack if you want to destroy magic armor, but your weapon is primarily physical.
