Second, even if you were that off the wall, run an emulator on your PC, and output it to the big screen. Most newer PC's can, most emulators have the option to add scanlines or similar effects.
Third, the reason old guns don't work on HDTV's is not lack of scanlines, it's the entire process for displaying the video. LCD's use progressive scan, CRT's used interlacing. Now for instance, you can set your cable STB to output 480i, but your HDTV actually then deinterlaces that signal. It's automatic, you can't turn it off, otherwise you'd get no picture at all. So even if this device somehow interlaced the picture, your TV is just going to convert it to progressive scan. Even beyond that, there's an issue of timing as well. The flicker rate would have to be close to what CRT's used, as well.
I personally think it's impossible to get original guns to work. It is however very possible to make a new gun that works on an LCD, perhaps with sensors, and then communicates with the console. The drawback is that you'd need a new gun per console (NES, SMS, SNES, GEN, PS1, PS2, etc.). Or the manufacturer would have to program code to talk to each of those consoles into the gun, and then build an adapter that would fit each of those consoles, like a Radioshack power supply with multiple, swappable connectors.
