Melee weapon idea.

Is it possible to somehow to change the elemental damage of a melee weapon? Kinda like how you can dip arrows into the tubs for a different arrow type?
I was thinking having it almost like a poison potion type thing; have the base elements in a different potion and you can apply it to your weapon for different affects It could either last forever until you switch it out or It would have limited amount of charges like a poison weapon.
If the affect lasted forever have like crystals that could change it by double clicking the crystal and targeting the weapon. These could be placed on the token stone like arrow tubs.
