Pablo, I can't speak to accessibility, but since what I'm going to mention is open-source software there's no harm in trying it. PDF Split and Merge, AKA PDF Sam, is a great little tool for doing what you propose. You can take any PDF file and split it apart at specific pages, creating "chunks" of the file. You can then merge those chunks back together to reshuffle the pages to suit. The current version is 3.0.1, and looking at the interface I have my doubts regarding current accessibility, but give the latest a shot. I can also send you either the MSI installer for version 2.2.4 or the exe installer for 2.2.2, both of which would still meet the need and may be (more) accessible with their older style interface, which involves a lot more "real" buttons and edit boxes.
It's a great little tool, but only the latest version is out there for download. I archive in case I need to go backward for some reason. Brian
