Duck Hunt on LCD overhead projector?

I'm putting my overhead projector on my balcony (live in a condo), and I got a big white space for it.
I use an amateur projector, it's an pretty new Canon projector, really bright stuff and I have an LCD screen hooked up to so it projects that, I've been using it for movies and stuff for a while and I decided to put some older systems onto it.
A big thing I want on it is an old NES, we love the 360 on it (can't risk the PS3 in case of slight rain while we play) but a NES would be awesome. Question though; is it possible?

I'd say turn the brightness up on the projector as much as you can, and the lights in the room down all the way if you're going to try it.
The facts are as thus;
A. it probably will not work because it was designed to work in a very specific way with crt televisions.
B. It could (slim chance) possibly work because the gun is a camera that looks for a specific on screen image.
There is no other advice at this point then go out and try it. you have no other way to know.
So as not to be wasteful of a post;
If you're really truly against setting up your rig solely to test out duck hunt, why not just test it out real quick before your buddies come over next time you set it up for something else? it can't take longer then 30 seconds to connect the Coaxial RF cable the NES uses as a video/audio out...
Duck hunt and other light gun games don't work on progressive scan devices. The reason is how the game is designed to work. Here comes some science. When you pull the trigger in duck hunt the ducks are redrawn as white boxes on a black background. If the white box is seen by the light sensor, you score a hit. Now in order to tell which duck you hit the CRT aspect comes into play. A CRT works by drawing in Pixels starting at the top of the screen moving from left to right. When you pull the trigger the NES also takes note where in the clock cycle of drawing on the screen it is. This lets it calculate how many lines have been filled in and where on the screen the white box the gun saw is. So it should work if you have only one duck and sufficient contrast, but two ducks will screw with it, you'll get strange effects like shooting both ducks at once(or just missing depending on how the game is coded)
