I don't think it will help at all. It might actually confuse the sensor in the gun. Something to consider is wiring up your own IR LED's at the corners of your monitor instead of using the light bar. When I used my Wii (which uses the same tech as the Aimtracs) on a projection screen, the regular light bar didn't work cause I was so far back. I just powered up a couple of high power white LED's and placed them at the corners of the projection screen. Worked like a champ.
