If you do do it like this, be sure to leave the drive you are replacing attached to the array. Otherwise, in a raidz, if you were to suffer a disk failure on one of the other disks whilst replacing/growing the array, your raidz would be badly broken. Other than that, I can thoroughly recommend this method, I had data on 2 x 1.5 TB drives, and set up my raidz initially with 4 x 1.5 TB, 2 x 0.5 TB, copying data off the 1.5 TB drives onto the array and replacing each 0.5 TB drive when done.
