Have Pages (above) & applicable Subpages (below) header image?

I currently have this setup for my header area configuation: %logo %page-center %bar1 %image %bar2. I would like it (in effect) changed to: %logo %page-center %bar1 %image %bar2 %subpage-center.

Now for more detail:
I'd like to have a page menu of subpages below the header image and 2nd bar. When I click on the parent page above the header image, want the subpages to appear below the image (I'm going to remove the drop-down feature of the parent nav menu).

I've tried searching for the answer in previous posts, but have come up empty. Any help would be appreciated. Thanks.
