Double post, because I thought, this may be a new feature wish, if it would not have been possible (as Zvoni thought and me too)New feature wish for customizable icons? I think this is not easy, and has little benefit. Better: If you miss an icon propose which one among the huge icon collection that we have in the images folder should be used (it must be unique, of course, and should "fit" somehow to the others logically), or describe or sketch how it should be modified, and submit it as a feature request to bug tracker.
