I've proposed Miller to Long Island in the past and I think there's a fit. That being said, I don't believe Pulock would waive for Vancouver.
He was drafted by the Isles and the Isles are two seasons removed from taking Tampa to the brink the semi-finals series 3-4. The season prior they'd actually made the conference final.
Vancouver is, well, a mess.
I reckon any Miller trade to the Isles would probably involve Bailey coming back.
