I hope it will be. I'm talking to a CNC company to get the prototype made. It's an all mechanical mod the size of two 18650's next to each other (plus the cap). The tank is a full 5ml. The button lights up when pressed. And it's water proof (meaning the tank/wick/cap will flood, but the electronics will be protected.)
I've also designed a second base that has a window for an LED screen and amount for the ProVari circuit board. When that base is attached, it's only an 1/2" taller.
That's the APV I really want. A device that can be Mech or a ProVari, with a 18650, a Zenesis Atomizer, a 5ml tank and water proof. I'm a Dive Master by passion, and I'd be scared to death to take my ProVari with me on a dive boat. Oh, and small!
here's a pic with optional base for electronics:
