Not quite. An LPE can only be used against your system by logged-in users.
To make a blended attack that can read /etc/shadow from an LPE, you need either SSH access or a remote shell vuln, not an arbitrary file read vuln. Holes that expose an unintended remote shell are quite a bit rarer than ones that allow a service like Apache to send you any file their non-root account has permission to read.
It’s a bit like calling lightning to find a system where both types of vulnerabilities are available at the same time.
