Believe it or not, there is an application that can allow the windows to chemically change, but that is a type of light effect, the more light, the darker, sorta like glasses that get darker with exposure to sunlight or light in general. I suppose you could modify the registers and include a thin glass on the inside....something you might find on Pimp My Ride. If anyone could do it, they could at least try. The only novel thing I have seen is bullet resistant (as opposed to proof) glass fitted on a BMW.
As an engineer I would say that it is technically possible, but I would buy the Lotus instead.
