What about converting each single-page document into XObject via 
\pdfximage primitive? In such a case, specified pdf page box is 
sibstituted by BBox of resulting XObject (image), and positioned on the 
output page in any way you want. AFAIK there is

\pdfoptionalwaysusepdfpageboxes

parameter which allows to control, which page box is taken into 
consideration while embedding pdf page as an image. Are all these pages 
to be cropped in the same way?
