I have posted something with similar idea here: http://lists.freebsd.org/pipermail/freebsd-security/2012-August/006547.html But this is different -- you can't have only /boot unencrypted because it requires / and /usr be available at very early boot time. Personally I'm not quite concerned with / unencrypted -- you could reveal /etc/master.passwd in the worst case but sensitive data can be stored in encrypted partitions.
