Peter, Don knows much more about your paticular project than I but I can show you how I used decals similar to yours on an airframe with lines and raised rivets.

Once the airframe is ready to start the panel line layout, tape your decals in place using a bit of masking tape. Do all of your panel line layout and then remove the decals leaving it smooth under them. Apply your rivets, again leaving it smooth under the decal areas.

Now paint the airframe, install decals, use some panel line tape for reffernce and apply glue rivets over the decals. Then remove tape. You will not notice the absence of panel lines on the decals and the transluscent glue rivets take on the color of the area that they are applied over. I then flat cleared the entire airframe.

While not dead to scale, the end results are good enough for all but the most rigid scale enthusiasts. Here are a couple of photos and a lot more can be seen on my B-25 page that is attached to my homepage below.
