Modified Lightning Rods should deter Phantoms

I believe one of the long-standing issues that players experience with the phantom is that it brought hostilities to the overworld that you couldn't opt out of (like with previous mobs) by simply by building defenses or lighting things. Sure, you can make a roof, or just sleep, but for players who like to build and experience the whole day/night cycle, it becomes an annoyance.

What if the copper lightning rod could be used as part of a user-built structure (like the conduit) to create a defense against phantoms? This would let players opt out of that experience within a certain radius (solving a common complaint for base-builders) while staying in the theme of the game. If placed over an area, it could zap phantoms or prevent them from spawning for players who were under the glow of this new structure.
