Ultrasonic/cavitation humidifiers create water droplet mists without a heated element. A piezoelectric ultrasonic transducer membrane vibrates faster than the speed of sound in water, and cavitation bubbles form that throw mist droplets into the air when they implode at the surface.
Propylene glycol (0.042 Pa-s) and glycerin (1.412 Pa-s) are more viscous than water (0.001 Pa-s). But glycerol is essentially non-volatile below 310K, and the vapor pressure of propylene glycol is less than 1% that of water. But if you're not depending on heat-vaporizing the carrier solution, you could add water to make it cold-mistable by ultrasonic cavitation. Both of the usual bases are miscible in water. Your cold-mist e-juice would not be compatible with regular vaporizers.
Maybe an impeller recirculating the fluid through a venturi could also lower the local pressure enough to help induce cavitation. I'm not sure how a laser would help, though.
