Hi,

when I think about it...

It might be possible to convert the mosaic data to independent channels
with transparency:

source:

RGRGRG
GBGBGB
RGRGRG

to:

RTRTRT
TTTTTT
RTRTRT

TGTGTG
GTGTGT
TGTGTG

TTTTTT
TBTBTB

I don't see any principal problem with processing such images with nona
and enblend.
And if you do stack of multiple images shifted by 1 pixel, the result
could even have higher resolution than input.
