Mod that changes conspicuous and inconspicuous?

[Tazor]

With the current stealth mechanic conspicuous is just free points and inconspicuous is useless. As the zombies roll way too often in order to determine if they spotted a player or not on the tile.

What would be nice is if these perks changed the DISTANCE at which zombies spot you. So for example with conspicuous they would spot you from the base range +2 tiles. With inconspicuous they would spot you from the base range -2 tiles.

Any mod that does anything like this?
