I recently met a guy who does custom sports figures. He has a closet full of nfl sports figures he got wholesale off of ebay and customizes them however people want. He hasn't done any Michigan guys yet. I was talking to him about doing a Desmond striking the pose but I don't think he has figure in that position. He repaints the whole figure and mounting. He does whatever colors or numbers you want down to the Nike swoosh or addidas sign. You can be specific as to what jerseys you want (if you wanted to do woodson in a road jersey he could do that jersey opposed to the current road jerseys).
His website is http://dmanscustoms.com/
It has pictures of ones that he has done already, pricelists, etc. I know he is out of town for the week and it is one guy and his wife that does them. It usually takes a week or two for him to fill out an order. Just email the guy, he is very nice and personable if you are interested in getting one. When I have a place to put one I plan on doing one. I'm sure he will take pictures of the Michigan ones when he gets them done and post them.
