My preference would be to try modifying the borders. Alternatively you could try removing the .tga file that is being used and return it to the default border, then proceed from there. That might be easier than reworking graphics or recoding the All-in-one. If you would like, I can look into this possibility and let you know what would be involved.
It turns out that this is very easy to do, go to the bottom of the xml file and look for the following line:
<Pieces>DrakPlayerwindow_Back1</Pieces>
Delete this line, then set the transparency to true and the border to true. The only other thing you will need to do is add some labels in front of the graph bars which were previously in the background graphics file. After that, just make the changes that adds the border that you want.
If there is anything else I can do to help, let me know.
