Wow. The MLU idea is a great one and probably pretty simple to do also.

This is pure speculation, but I suspect that what Pentax have done is performed the Bayer interpolation with 16-bit precision and then kept the extra information. It's not "padding" as such - dropping the four least-significant bits would be equivalent to a second stage of quantisation, introducing extra quantisation noise.
RAW files are just that, RAW sensor data, pre-interpolated. Case in point many other cameras on the market that use this sensor manage to provide RAW files of a size which can be directly related to the fact that they only contain 12bits per pixel.
However! In practice the effect might well be very small, making the trade-off worthwhile to gain an effective 33% increase in memory card capacities.
The effect will be 6.31M pixels x 4 bits (3.16MB) per image and more if compression was introduced too.
Personally my first target would be to implement something like proper MLU support...
This would be another great upgrade.
