I do not feel as though anyone being tricked into believing someone died is a good idea, in fact there are alternative ways to get some of the same information. If I was a researcher and I was surveying the reaction to death I would visit local hospitals and sit in the ICU or Emergency Room waiting areas, where real results like this happen often. If I were unable to gain the information I needed from sitting around hospitals I would visit a local funeral home, where families visit daily and conduct my research
