Yes, you can do that easily. First split the V3update.bin into its constituents using dd:
file=$1
out_dir=$2
rm -rf $out_dir
mkdir -p $out_dir
dd if=$file of=$out_dir/zImage bs=1M count=1 skip=1
dd if=$file of=$out_dir/ro.fs bs=1M count=6 skip=2
dd if=$file of=$out_dir/root.fs bs=1M count=44 skip=8
dd if=$file of=$out_dir/logo bs=1 count=240000 skip=$[1024*1024*52]
dd if=$file of=$out_dir/jffs2.fs bs=1M count=2 skip=53
Then mount ro.fs and root.fs as usual. Then copy their content (only using rsync -AHPSXa rootfs/ myrootfs to preserve the hardlinks correctly). Then, just edit the files (or replace etc etc) and then remake the images like this:
# mkfs.cramfs -v myrootfs myroot.fs
Then remake the V3update.bin like this:
mkv3update --write-hanlin=My-V3update.bin +zImage +myro.fs +myroot.fs +logo +jffs2.fs
(the mkv3update command comes from OI or you can write one yourself as the firmware image layout is well documented on OI webpages)
