A simple script should do. The following is untested:

find /large/dir |
while read name; do
     new_name=`echo $name | sed 's/$name/$new_name/g'`
     [ "$name" != "$new_name" ] && mv $name $new_name
     if [ -f "$new_name" ]; then
         sed 's/$name/$new_name/g' < $new_name > /tmp/rename.$$
         mv -f /tmp/rename.$$ $new_name
     fi
done
