I think I would be concerned about bonding.

I agree it would somehow need to be bonded.
Not specifically addressed in our code. I have used a metal weather head for SEU cable, never bonded it.
When you twist up your neutral and bend it down so it comes out the notch below the inserts it contacts the metal.

I'm thinking that a metal weatherhead is not listed for use on a nonmetallic raceway.
