[gdal-dev] Embedding external TIFF overviews into GeoTiff

obviously Gdal can't swap external overview file(s) into internal in
GeoTiff format, am I right?
I would like to use my own overviews in some Geotiffs and use them in
Geoserver, but Geoserver can't handle external overviews. How
complicated it would be to incorporate such a feature into Gdal? I don't
mean that it would have to be included into new releases and it wouldn't
have to cover more than just GeoTiff format with "normal" RGB-images. I
could try to taylor my own Gdal-version, but I am not sure how big job
that would be. I am not so much familiar with C, so the outcome
would/will be a little bit 'quick'n'dirty anyway.
Another approach is to embed GeoTiff tags into multipage tif, I guess. I
know I can dump Geotiff header into file with listgeo, edit Tiff with
some tool and copy header back with geotiffcp, but AFAIK this system
doesn't support overviews, right?
with best regards,
