I was kind of disappointed the mask Morokei would not let me use the mage armor perk anymore, so I thought I'd find a way to mod it to have 0 armor. Does anyone know how to do this, or if there is another way to circumvent this problem?
There's a mod that makes certain unique gear enchantable that was made to satisfy nearly the same request at the Bethsoft forums. It doesn't do exactly what you're looking for, which is to just alter Morokei to be a clothing item instead of armour. Instead, it removes the existing enchantments from a selection of unique items (including the mask) so that they can be custom-enchanted. The mask has also be set as a cloth item.
If you're good at enchanting and want to custom-enchant your Morokei, this mod will do it for you. If you don't want to mess with enchanting, then you'll have to keep waiting for a mod that just changes the mask to be non-armour.
