I have put a lot of thought into this idea.
First off, the red/blue gel filters WILL work but not well. The human eye can't see infrared light however there is a small spectrum of "near-infrared" light that we can see. It's that small amount of light that can give you limited vision.
Second, though one could place a screen in front of your eyes it is very unlikely that you would be able to look at it for long periods of time without strain. To fix this, a lens would be needed. If you have the money
this would be your best bet.
Third, poor depth perception other visual impairments impairments will always be a problem. Even the military's true night visoin googles have them. Whether it's peripheral vision, depth, or clarity. Something will always be lost.
As for how to fit this all in the helmet, there are several ways. As with most permutations, IR lights can be on either side, and Myvu glasses can be within the helmet connected to a pinhole camera either hidden, or in the place of one of the lights. My favorite however involves the new Halo Reach helmet by Rundown (
found here). The thing (for lack of better words) on top of the helmet seems to be a device that comes down onto the visor. I think this would be a great place to store the IR LEDS and the camera. It could also hold an LCD if enough distance is provided to focus on it.
Anyway, hope this helped and sorry for the long post.
