Well I asume you are wanting to use USB to power the back light system. Personally I would be thinking of using EL Backlight foil to go about this project although I am not sure if it would play nice with the 5v from USB power instead of 12v. I am not saying that it won't just that it might not.
Have you considered drilling out an extra hole, running a separate cable along the length of the USB cable and then heat shrinking it into one nice manageable piece? 

Not a particularly elegant solution I must admit but you would get a strong back light and it would only be noticeable if you move your keyboard a lot\ can see your power outlets.

You want the keys to light or the bit behind them? It doesn't look like it's made of transparent material (or is it?) - so you would be looking at a total rebuild I think. L
