Back when you had just formatted the disk, yeah, probably. Now, with the additional changes, I would say no. Sorry. :(

The single disk will essentially degrade the performance of the whole pool, because it represents a unique (100Mb/sec, typical) transaction group now, and if you lose that one disk you will also lose the entire pool since it has no redundancy.

That’s another reason for FreeBSD-based front-ends to ZFS like FreeNAS. The GUI adds some seat-belts to prevent users from trivially doing things like that. On the command line, all bets are off.
