I was just thinking...IIRC the interface stuff is greyscale, and you set the color values as they should appear, right? Are graphics like screen borders, buttons and so on hardcoded, or are they replaceable, too? If you, you could come up with new graphics for them in a style different from the WCP one while keeping the color settings as you have them now.(Rather simple ones would fit IMO, such as the screens in WC3, without all those buttons and what-not which serve no purpose anyway)
