It seems to involve the mind split paradox. I remember the RB's advices against to stay near physical body during AP. He alerts on dangers of a feedback process. By other hand, there exists the risk of to went mad, since madness are related to treatment of paradoxal and illogical situations.
From a critical viewpoint I think what if great amounts of mental energy are required by simple visualization process, double visualization process ¿how much energies requires? I think it would be necessary to have two brains... don't you? I think it would be really overwhelming for projector.
