You could get a bit better than stereoscopy by using say 4 cameras. Plus since it is on moving head, you could use a bit of surface from motion techniques. You could also make the cameras rotate on their own (or mirror - like DLP; or lens), like eyes do, to enhance the result when head does not move. Loads of processing power required... solvable. Now the real problem is the display of sufficient brightness and colours. Some sort of future translucent LED screen could do it, maybe. DLP can do it at big cost and with bulky projectors. Current picoprojectors are not very bright... And then three is a focal length problem to solve to have sharp image and good depth range while not messing with accommodation.
