Sell the idea, or collaborate, with Double Fine. Make it Horror/Adventure point and click with some FPS aspects. Would be interesting to start in FPS mode and then be forced into the 3rd person cinematic point and click (which would be easier for people to handle rather than the first person controls). But you could have levels that force you back to FPS, like someone else said about sensory modes where you're bumping around listening to sounds (though that may be difficult), though the different types of cameras (x-ray, infrared, ultraviolet, etc.) would be interesting.
Still wondering why the guy couldn't grab a networked wireless camera and strap it to his head so he can see in the first person again. This is a cyberpunk world where he's got neural network connections in his head, there should be wireless cameras he could strap on. Maybe that could be a level, he finds the wireless camera, straps it on, completes the level and then it gets smashed, fries, or the battery runs out.
