Technically, ILS is independent of the lights and beacons. However, I guess in carrier world, a higher frequency equipment is used due to EM / space / precision requirements.
However, when we get a GPS equipped version of the Hornet, it might be possible to construct a semi-precise approach using manual waypoints for airfields not equipped with TACAN. It won't give you full localizer/glideslope capacity, however you can do pretty precise approach with bearing / distance information with enough practice.
