I do not know of any such scripts but a possible solution is to use
nullfs. I personally install all needed ports into the base system and
use nullfs read-only to pull everything into the jails. Almost
everything, files from /usr/local/etc are manually copied as needed into
each jail. It lowers the disk usage and reduces risk due to most files
(even system) being read-only.
You just need individual /etc/fstab.<jailname> files like this:
/bin /usr/local/jails/<jaildir>/bin nullfs ro 0 0
And similar lines for these (at least all that you require):
/boot /lib /libexec /sbin /usr/bin /usr/games /usr/include /usr/lib
/usr/libdata /usr/libexec /usr/local/bin /usr/local/cyrus
/usr/local/etc/periodic /usr/local/etc/php /usr/local/etc/rc.d
/usr/local/info /usr/local/lib /usr/local/libdata /usr/local/libexec
/usr/local/man /usr/local/sbin /usr/local/share /usr/sbin /usr/share
/var/db/pkg
A basic jail runs about 9MB (mainly /etc and /usr/local/etc). Does this
help?
