OK I checked the cab files and read the mode9 file that governs the icons, compared to stock file.. seems that they created new "invisible" references to get these cleared. So I would suggest installing the sketchy icons set up... then reinstall your icons. This would show your icons and heros but leave the invisible files and the references working... I know it will work because I've switched out icons since installing sketchy cab wihtout uninstalling sketchy cab and the shadow/second icon stays gone. It's your cleanest bet. The only way it wouldn't work is installing a cab that includes file 61f866ab_manila which would overwrite the instructions. Here is a link to the sketchy pack..

If I was more comfortable readjusting the file I would but the one thing I tried (deleting reference to the "on" state) resulted in a cycling manila load....
Also I am attaching the single file from the skethcy group but I really think you need the "invisible" files that are referenced for it to work so probably best with the entire setup.
