Yes, it's possible. The one part to keep in mind is that Rear uses
files (grub config,...) from the restored backup to finalize the
recovery. You should probably use BACKUP=REQUESTRESTORE and rsync from
the backup server when Rear prompts you to restore the backup. When
that completes, just tell Rear to continue.

Network configuration can be changed from the kernel command line.
This can already be added in local.conf if you know it before the
ip=${mgt.ip} nm=${mgt.netmask} gw=${gateway}
