Here's a sample using V4. I used two Blender nodes, with Blending set to 1.0, one node for color and one for bump. Victoria's textures go into one input of the Blender, and the overlay into the other. The Blending input is controlled by a mask.

The basic color blending concept doesn't need displacement, but in this example I could have added some displaced seams to make it look less fake.
