Actually I've played hide-the-GW-skulls on several projects. I used the Garden of Morr cemetery in both my Victorian and Gangster era cities. In that case I once again hid the skulls using Milliput, not as rock but as shrubs covering the skulls. In my spaceport collection I used the GW reactor and hid the large skull under a technical-looking part taken from another kit. My guess is that as long as GW produces a great looking item that would enhance one of my projects, I will do my best to hide the skulls so I can incorporate the piece in my project(s).
