I thought of doing this, but I do wear a full-face/modular helmet, mostly to keep from catching any more stinging insects. During the ride, I zip it up either in the jacket pocket, or tank bag. Pull over every 60-90 minutes and stretch legs, but vape rather than inhale the .... or two, as I've done in the past. During shorter rides, I never felt I needed to light up a cigarette while on the move.
I had thought about a lanyard type setup, but thought the drip tip might fall out, or the clearo unscrew itself, due to all of the wind buffetting. Maybe some sort of bent/right-angle drip tip, and adhere to inside chin bar of helmet?
