Its possible, but as with any wallpaper the odds are that the water in the plaster will dissolve the wallpaper paste and the lot will end up on the floor. Don't do it is our advice and see our project on stripping wallpaper.
As the doctor says mate its possible but ive never done it with out it falling off and i've done a lot of it. As painful as it is youll have to strip it mate.
