That would be cool, when i played Oblivion, i always used mods that made the night darker, the dungeons more darker and used the Half Vampire Race mod, aswell as the vampires sight toggle mod that made it last until turned off and it had a life detect attached to it, that was cool, but on Skyrim, to be truely stealthy, you have to sneak around enemies in 3rd person to know where they are facing and such. As an archer that is near impossible to do, since the crosshair is in the wrong place, while in 3rd person. So, i would like what you want also, it would make my gaming more fun.
