I am so sorry to hear about your house damages.
Just a thought on the brighter side:
I have an idea that may work, if you still wanna to hang on to some of your favorite wallpaper. See if you or someone else can cut out a large piece of your wallpaper. Frame it and hang it up with all of your other frames on the wall. It may work ya'. You will never know until you try it! ;) That way you will have some of the same actual wallpaper to still admire! And new paper underneath to grow to admire.
