Yes, the PDF is a complete description of a number of pages.

It is possible to change some things by pre-pending some Postscript to change the meaning of some verbs, though it’s so long (couple of decades) since I last fiddled at this level that I can’t remember the details. So you could turn pages around (rotate the content by 90˚), but that won’t reflow any text/re-arrange the contents.

One trick I do recall doing was where we printed inbound faxes on our SCO OpenServer system at a previous job. I changed the meaning of the “showpage” operator so that instead of just printing the currently imaged page, it would add a header to the page with key details (date, time, number, etc) and then print the imaged page.
At the same place I also did a custom text-ps script, adding in options to use some of the printer specific features we had on our printers - like doing A3 landscape on a laser instead of printing to the old green lined fanfold.
