I intend to keep most of his personality intact. Awkward, Virgin, Cheese-loving, humor; however his world view will be a little less naive and more jaded because of his time in the circle. The biggest difference would be more of a desire to be king. Still loves Duncan though.

There's a fine line between a remix and a complete scramble. I would recommend keeping as much of his personality intact as possible if you intend to play him as a mage. We still want to recognize him as Alistair, after all. If you want him to desire the crown, for instance that implies a huge change in personality to the point that, combined with being a mage, you might as well just roll a unique character. I don't want to say you can't do it, because I do not want to micromanage character creation like some kind of dick-GM, but just be careful. 

Additionally, I am very glad someone's doing this one. The irony in this particular remix is just too delicious to pass up.
