If you're going to pursue this, I would recommend writing a separate
filter. You can now write rasters with writers.raster, so the filter can do
whatever and just pass the raster on to the writer. You might also look at
filters.zsmooth (which seems to be missing from the doc index). It's not
exactly what you're looking for, but it could be modified to do something
quite similar with not much effort. It only runs in standard mode.
