I would recommend adding a new disk, reinstall the OS on the new disk with LVM, and then moving over any data that was required after installation. You may be able to do this in rescue mode within a chrooted environment, but things could get messy. Add the new device, build the lvm stack, copy over the data then chroot into the NEW lvm root. Mount everything appropriately, recreate the initrd and re-install grub onto the new disk. Go in with the expectation that you may be fixing things after the reboot from rescue mode.
