It's possible, and if it hasn't been done it mightn't be far off.

There certainly is. In the past I have used GEOM Based Disk Encryption  
(GBDE), because my computer had already been partitioned I used GBDE in  
combination with mdconfig (created a 2g file with dd, used mdconfig to  
configure it as a device, then ran disklabel and newfs on the md and set  
it up with GBDE). This was using 5.1 at the time and it ran extremely  
well, the only problem I ever encountered was when copying several hundred  
megabytes of data to the encrypted disk, it would then cause the whole  
computer to lock up, this could have been because of the use of mdconfig  
or my laptop being dodgy.
