An SM-6 on an F/A-18 is disturbing but unattractive

Would putting SM-6 missiles on F/A-18s make sense?

He dislikes the idea and would rather use an off-the-shelf long-range air-to-air missile such as Meteor than force a ship-launched missile into an aircraft role.

Putting an SM-6 on an F/A-18 is described as disturbing and not sensible, even if plausible use cases can be imagined. Ship-launched and air-launched missiles are designed around different assumptions. Adapting the weapon could produce an expensive and awkward fit. An existing high-end air-to-air weapon such as Meteor is preferred.
