If you do it this way each color will get different interpolation for each 
color (because different alpha channels) and this will results in color 
seams.
The next problem is that after remapping the Bayer pattern is destroyed. 
With the destroyed Bayer pattern it because impossible (or at least very 
difficult) for the RAW converter to demosaic the data now to get the final 
image.

(An alternative approach would be to demosaic the image data, then remap 
the data and then mosaic the data again to get the RAW again. But then you 
will loose resolution. So this is a no go.)
