Unfortunately there's not too much of a market for this sort of thing. It exists, but is called a scan-back, and is damn expensive, due to the sensor approximating the size of the film that goes in. Besides, the camera really has nothing to do with the film's feel: It's all process and lens. Half of that has to be replicated with photoshop, meaning that any lens that needs to be used, can be taken to a professional to be attached to a mount for any camera. There's a considerable homebrew scene for retrofitting lenses to cameras: bellows are very in right now.
