IRNV mechanic change? Intensity over time

So there's been a few suggestions to how the IRNV should be changed or just removed completely. But while playing in the game and noticing that soldiers further away were more obscured I had an idea come to mind. What if the way to balance the high visibility in the brush was not to change the reticule, or by how much you can see people, but rather the length of time of target acquisition itself? Rather than seeing people immediately at a distance, it took time for the image to "burn in", thereby increasing the time it takes to notice people. The closer one is the less time it takes to see them, the further the more time you have to stare in that direction before you can notice them. Spec ops camo then would lower the time it takes to start seeing people rather than being completely invisible, so the balance to choosing that camo would be being seen faster without irnv, but slower with.

Feedback on this idea? I doubt since the path with the irnv "nerf" is coming soon that the devs will pick this up anytime soon or if they already chose to do this. Kinda wondering what other people think.
