Removal of mirror vdevs is planned _eventually_, but last I spoke to Matt about it it wasn't a super high priority.
If getting rid of the mirror vdev is important to you, you should probably be scheming on how to make a backup/destroy/recreate happen. Especially since you appear to have set those SSDs to ashift=9. That absolutely _murders_ the performance of Samsung 850s. I've seen properly-ashifted _rust_ drives outperform Samsungs on ashift=9.
