Absolutely.
You can use tiffcp to copy only some subimages, eg.:
tiffcp in.tif,0,2 out.tif
To identify the subimages you want, write a shell script or batch file that
parses the output of tiffinfo, maybe with a bit of perl or awk.
Alternatively, take the tiffcp source code and tweak it to do what you want.
Or write your own code; that isn't too hard if you know that all your TIFFs
are tiled or not. tiffcp already knows how to take care of both strips and
tiles and conversion between the two formats, which is the main reason I find
tiffcp a bit hard to read.
