Hi Theo, since it is a detached header, you could probably do a mapping to file from the raw sectors, using losetup like this losetup -o offset --sizelimit <header size> /dev/loop0 <dev_raw_disk> and then use that as the file-argument for the detached header. I would say that this is exceedingly "hackish" and probably asking for a lot of potentially painful problems. You could probably also (even worse idea) use LVM to combine the sectors for the header and the ones for the data into a complete LUKS device (i.e. no detached header in the final thing).
