Instead of having monsters, projectiles, and pickups glow, make it so only frames tagged as BRIGHT will glow.
This would more closely mimic a true night-vision system, and also make the appearance of things like missiles more consistent, because they wouldn't lose their projectile state when they die.
Making the screen green without any further enhancement is rather pointless. It turns a powerup item into an obstacle players would hesitate to use in some situations.
When I added this effect I wanted to turn the light-amp into something useful and that included highlighting some objects in the map that are of interest to the player.
Therefore, no, I won't change the current behavior. Remember, you aren't forced to use this and can always go back to Doom's stupid fullbright effect.
