The page size is actually dynamically adjustable in Canvas.showPage, there we 
check the user given size and dynamically modify the PDF page size to allow for 
cropmarks and exotics.

My guess is, you could dynamically change canvas page height in a derived 
class's showPage if you can push the needed size onto the canvas in an endOfPage 
flowable.
