Would this be creepy/stalker-ish?

I think it's fine to add her as a friend on Facebook. It doesn't really matter if you add somebody on Facebook as it usually just taken as 'They want to talk to me' rather then 'They want to be a good friend and talk a lot' (It can be made that if you push it) you don't even have to delete her at the end because chances are unless you are talking to her a lot and then just stop (You deleted your account) she will notice. Her personality will play a big role on how she sees your friend request.
