It would be fantastic if someone could create a mod that creates a helmet overlay effect, similar to what was implemented in Project Nevada for Fallout New Vegas. I really loved playing with it in FONV, The addition of a stronger headbob effect would also do wonders in immersion for me. Not only that, but i'm aware that someone is working on a 1st person body mod as well. With all of these mods combined, it would make Skyrim's first person experience truly awesome! :)
