ZFS "copies" attribute could be used to make this easy, but with all the talk of kernel panics on drive loss and non-guaranteed block placement across different disks, I don't like ZFS copies. (see threads like http://mail.opensolaris.org/pipermail/zfs-discuss/2007-October/043279.html )
The bottom line in my opinion: Yes what you are talking about is a big hassle to create, and yes it is a big hassle to maintain in the future. Instead I'd buy another cheap ($99) 500GB disk and RAID5/RAIDZ them together for a clean and easy 1000GB of space. The end!
