I've only ripped down wallpaper with no intention of saving it... its not difficult, just quite time consuming and frustrating... you're costs will be almost all labor... and to save it, probably a lot of labor.
I agree with LeviDIY, it would be a lot of labor. Re-hanging it would be tricky when it comes to making the seams look perfect. If the individual strips of paper stretch even a little bit when they're being removed or re-hung, the pattern will be difficult to match at the seams.
It mostly depends on the quality of the paper and how well the walls were prepared before the paper was hung. There's a product called 'wall size' or 'wall sizing' that can be painted on the walls before the paper is hung. It allows the paper to be removed later in full sheets and with no damage to the walls.

It must be very special paper, I really hope this works out for you. Good luck.
Do you know approximately when the paper was hung, how old it is or the manufacturer?
