There is a, simple, better method:

create your new loopfs (40M)
# dd if=/dev/zero of=/tmp/new.img bs=1k count=40000

mount new
# mkdir /tmp/dest
# mount -o loop new.img /tmp/dest -t ext2

mount old loopfs image
# mount -o loop old.img /mnt -t ext2

copy old on new
# cp -a /mnt/* /tmp/dest
# umount /tmp/dest /mnt

Now, you have a a new bigger loopfs image.
Hope this helps.
