It's already somewhat like that, Slappy. The atty is a short unit consisting of the battery connector at one end, and a ceramic cup/coil at the other. The wick plate fits onto the coil side, has a short center tube for the wick, and a flat side for the air passageway. A silcone gasket fits on top of that, and the whole thing slides into the tube.
With everything lined up correctly, and the right density for the wick, it doesn't leak. It's also extremely simple to disassemble/reassemble for servicing.
The only weakness I've found is with replacement wicking; I've had little success getting CE2 wick to work as well as the factory wick. Otherwise it is a seriously good (and simple) design.
