There was a very cool ability for warlocks in the Vigilante Playtest called Tattoo Chamber that allowed you to absorb a wand into a tattoo and activate it as if it were in hand.
I have no idea if it will still be there when UI is released, but it's similar to what you want and one of the best abilities warlocks had.
