My first attempt at a mod. 

Update: Slightly increased the chance of a successful pacify attempt, and massively increased the length of time and the distance you must travel before your victims will try to escape, though fast travel and lowering your weapon will still make them hostile.

This mod changes the intimidation, animal friend, and wasteland whisperer perks to remove the need to aim a gun at your target. The vanilla set up didnt really make sense to me and i wanted more of a sam fisher experience sneaking up on people with knives anyway, if you felt the same feel free to try this out.

You can pacify an npc without a weapon at all, (i think this is realistic enough given the charisma requirements and the fact that animals probably dont know what guns are anyway) but if you equip and holster a weapon they will return to hostile just like normal.
