Well, I don't know if you can add a hard drive and make it a stripe (RAID 5) 
with others that already have data...

Perhaps you could install the system in a free hard drive, then add the other 
two and make them a mirror. Then you could keep your data in the mirrored pool 
and the operating system, as long as some data that you don't care to be 
mirrored, in the single drive.

But as far as I can understand this is not what you asked for...
