Thanks to a converter found here I have been able to try and see what the Wing Commander Faces I made look like in Fallout 3.
The results are that it works for the most part. I could not find a way to get facial hair to transfer properly so the Paladin face did not work. Here are pictures from Fallout 3 showing Blair, Maniac, Who1 and Who2 as well as just as another test Winona Ryder. Also I notice in the case of Who1 the glasses did not transfer, but I think that's because glasses are a item in the game that can be worn.
