I think by "at one time" you still mean one at a time (a raid swap for each drive).
We have a bunch of filers sitting idle waiting for some back-ordered components, so I've taken the opportunity to "stress" them and see what breaks. ;-) On a quiet filer (no exports), I started with a two-disk configuration (it doesn't seem to mind having only one parity and one data disk) and hot-plugged four more drives in rapid succession without a `raid swap'.
The usual warnings on the first write to a new disk were logged, but then the filer complained about all three SCSI buses (only 9a was in use at the time). Beyond that there were no other difficulties.
