I'll see if I can replicate. Obviously it requires me to have a game go into extra time to test first!
You can copy over panels/player/player overview panel.xml, the whole panels/player/mustermann folder, classes/attributes_circle.xml, graphics/mustermann/attributes, and then define the attribute colours you want in the settings file. That will only do the player profile page, though, so you'd end up with numbers and regular attribute layouts in a lot of other places.
