I can't think of many changes other than making it weightless and attached to my body in some way that I don't have to move any limbs to vape. Of course it will also be self cleaning and self coiling, self juicing, and self healing finish, and since it will be attached to my body it won't need a built in beeping locator. But might want to throw in semi-permanent (user replaceable every five years) power supply that recharges itself without user intervention. But if downgrading from these "improvements" and going hybrid route I'd love to be able to change out the ceramic base and posts.
