Keeping Root & wp off when Upgrading Rooted Retail VZW Moto X with wp off to Lollipop

My Retail XT1060 VZW Moto X 2013 (non-dev edition) is rooted with a locked bootloader and write-protection off and running Android 4.4. I would like to upgrade to Lollipop (Android 5.1) while keeping root access and write-protection off. Is this doable?
