I was wondering if anybody would be interested in making this? Perhaps with a similar/same effect as the cowl in oblivion.

http://skyrim.nexusmods.com/mods/18386 looks nice... a bit more than just the cowl though.

EDIT:

An http://skyrim.nexusmods.com/mods/searchresults/?descr=cowl&order=DESC&orderby=date&page=1 on nexus with parameters:
Description contains: cowl

gave http://skyrim.nexusmods.com/mods/15242 which is more just the cowl

Lol.

In all seriousness, please do a bit of searching before posting. It cuts down on unnecissary posts and the requests that don't already exist get more attention.
