Projector height relative to the screen is a function of the vertical shift capability of the projector and the Panny is pretty generous. However if you decide to do a wide-screen 2.35 with an acoustically transparent screen on your contemplated false wall there are limits to keep in mind. If the lens is even with the top edge of the screen it will never be a problem doing the zoom method CIH. Check the owners manual. IMHO buy a mount using a 1 1/2 threaded pipe down pole and you can start with the shortest pole which is a couple of inches and swap it out if you need longer for under $10, Spray paint the Home Depot off the shelf pipe black.
