RAW without interpolation.
 
Is there a raw converter that doesn't interpolate when it demosaics?

Without interpolation, you'll have 1/4 of the number of pixels on the camera specs, but very high quality ones.

Each color pixel will consist of information from 4 sensor photosites.

You'd end up with a razor sharp image which only takes up 1/4th the size. Instead of 23MB files, you would have a 7MB file. Major file size reduction. Aliasing might be a problem, however.

Does this already exist? If it doesn't i'm going to start writing a script to do this. :)

Some good discussion on techniques, and why interpolation is used.
