Is the art of disguise possible? Options

[Foster]

First off let me say that I am not a modder, and have abosolutly no idea if this is even possible. However, I thought it was an intresting idea so I'd ask.

Would it be possible to create a disguise discipline, so that your character could be a master (or mistress if you perfer) of disguise? Yes, I realise that I've been watching a little too many caper movies, but the idea of being able to disguise yourself I thought was an intresting one. In other games I know it's easy enough to change the player skin, but I was thinking more in terms of a temporary change, which removes some of the penalties you get - you know, minor things like hair style or model head - by normal means or magic; you could even have some kind of mission impossible style mask available to purchase or something.

What use would it be in the game? Well, other than being cool, I was thinking something like removing (whilst in disguise) the bounty on a players head, or at least lowering it whilst in diguise. Once they're back to normal, then the bounty returns to normal. Could be useful for Theves guild/Dark Brotherhood characters, and the idea isn't totally out of left field - Jagar Tharn did it in Arena.

I'm just thinking of ways to try and get past every guard ever knowing all my crimes. So, opinions?
