Two interesting points there, since I do try bandwidth reduced imaging with colour sensors, and it is quite annoying.
The possible highlight recovery from using information from separate channels is possible in theory, but what software that handles that well? I was wondering about using that as like a single shot "HDR" sensor since the colour channels are each differently sensitive.
The resolution increase is what I'd really be interested in from any mono sensor. If you move away from the green channel, kiss goodbye to resolution. A mono sensor would offer 2x linear resolution, or 4x area resolution in that case. No more is your 18MP sensor working as a sparsely sampled 4.5MP one.
And as a very un-Leica thought, narrowband imaging potentially allows the use of lower quality optics, since CA effects are reduced. So I guess my point from all this is I wish someone did it a bit cheaper? Leica wouldn't be my first choice...
