Nic,
My first instinct is to create an post binding book along the lines of a high-end scrapbook.
You can stack large heavy bond paper and drill through the book block along the spine. Then, use metal posts to lock the pages together.
You can include the cover when you bind and let the posts show as decorative elements or you could bind the cover afterward and use it to hide the posts. All depends on the look you want.
Just a quick thought for something to explore.
