I'm reminded of the study where four guys who all thought they were Jesus were brought together. Each thought the others were imposters, IIRC. Don't think it'd work.
"While initially the three patients quarreled over who was holier and reached the point of physical altercation, they eventually each explained away the other two as being patients with a mental disability in a hospital, or dead and being operated by machines."
[EDITED to add: See also http://squid314.livejournal.com/324957.html which is only marginally relevant but anyone who finds "The Three Christs of Ypsilanti" interesting will probably love it.]
