Maybe some "cracks" in here figured a way out how to do it. But as far as i know there is no way yet to make specific icon names transparent or invisible... A possibility i could imagine is that you edit each icon that you make it a little "longer" and include the apps name into the icon, underneith the icon, next to the icon or wherever you want. It's the only way i could imagine how. But better wait for someone more experienced in plists.
Sorry that i couldn't help you in a better way but i know how frustrating it is to not get any answer at all
Good luck
