[gdal-dev] VRT - using 8BPP palettized tiles

I am fiddling with some old scanned (handmade) maps. In order to reduce the
size of the data, and since
the maps has a limited amount of colors, i figured that using palettized
8BPP tiffs would be suitable in this
I got several tiles that make up the whole area, using rgb(0,0,0) as nodata
(making JPEG compression
The idea was to use VRT to join these together, but since they all have
different color tables,
this is not possible.
Would it be an idea to implement support for an "expand option" in VRT, e.g
expanding to rgb/rgba ?
Not sure how many would need this feature though.
