Hmm. I further responded last night and it is not here, nor is the OP's additional post. I really, really hate this new forum software.
If I wasn't using a catalog plug-in, I would design the whole page with an image frame and the various text frames and the slanted text boxes. A complete page design for the various sizes. If one is using AI files (or PSD files, etc.), then link those in the page layout. The links are maintained in the library.
This whole page design can be dropped into the library and dragged onto each page as appropriate. If a change to say one of the slanted rectangles needs made, then the whole layout(s) are updated.
