Can't display vanity staff over rifle items

I'm sure this has been brought up before, but as a vanity enthusiast, I'd love to be able to equip a vanity staff despite equipping a rifle!

If you have a kreshal staff vanity... the purple aura an orb u get from wearing staff... stays even when u switch to a gun so what your after already exists >.<

I think what you mean is that you want to be able to see the staff vanity eventhough you are using a rifle? That is simple not possible because rifles dont work the same as staffs, they have faster firing for example. It would look wierd if a rogue for example would start shooting with a dagger
