I did make a request for this a while back and now I am doing it. Also I am posting it so I can claim the idea with something significant in hand.

http://i.imgur.com/eF6HZ7U.pngI have been getting stuff into the udk editor. I am having trouble with getting blender to export to udk. Right now I just have my textures with the original model. It does look bad, but it did give me the opportunity to fix my normal and spec maps.
Progress as of 2/19/2013
On hold till I figure out how to fix it and the documenation gets better.

http://i.imgur.com/cQfPjX1.pngTarget picture:

My goal is to simply recreate a combo of the mega betty picture and the one its based off of (the mega milk pic), simplifying the look, and put it in game. I started off by removing the pads, straps and armor from the mid section and then rebuilding the uv maps. I think I worked on her shirt by covering up the cleavage and getting the look right to match the original picture.
When I started on the texture, I decided to do a rough draft and then add in details in refinements later. However, i started to like the cel-shaded look I was starting to get. I might just run with it. Hopefully it looks good in game, if it does then doing a jet set radio Megabeth should be easy. I don't have the entire texture done, but its a good start. I still need to do the head and everything below the knees.
The only significant change I am still planning is to extend her hair out of her helmet. I want to get the look like she let her hair out around the shoulders so it would match the target picture.
I will need help getting this into game and possibly making taunt to go with the meme.
EDIT: after I made this thread, I realized I made a mistake on the shirt and she is starting to look a little to orange.
