Yes. If you value your data you shouldn't do that. RAID and backups are two very different things. Don't confuse the two. When you hot-swap a drive back in there'll be a resync putting heavy stress on all disks.
Also handling disks bare you risk damaging it without realising it. There's the very real possibility that you damage the disk you remove, the disk that remained in the NAS fails during the resync and the disk you hot-add hasn't finished syncing so is useless as well.
I'd suggest you rotate USB disks off-site.
