You seem to be looking for something like a werewolf, first a human, then a 
wolf, then a human again. :)

As Andreas Raab has already pointed out, what you are trying to do is probably

Why can't you just _replace_ the page in question (say, an instance of 
UserStory) by an instance of DeletedPage?
