Create a tool in ArcGIS Desktop to convert RGB to Colormap

ArcGIS is capable of converting Colormap rasters to RGB rasters.  Why not the other way around?  This would be helpful in reducing storage requirements by reducing bands from 3 to 1.  It would also make it easier to manipulate the display by editing the clr file since there isn’t a raster editing environment.

That could save disk space ...I inherited a 3 byte/cell RGB topo that could be a single band 0.5 byte/cell  raster with values 0 through 12 in colormap.
