HNL 787 pilots will probably just go to SEA, either move or commute. I'm not worried about those folks wanting to bid mainland 737 for the most part. Or if they really don't want to commute, bid something on the islands, whether it's 321, 737, 717.

Displaced 717/321 pilots would presumably bid 737 island base, which I think they'll need to cover all that flying, and also to not totally alienate the locals. Especially 717, be stoopid to make them commute to the west coast just to fly back, stay in company hotels, and do inter-island.

I'm kind of assuming that NB flying will be gradual one-for-one replacements with 737, so no significant net displacements.

Also most of the HA NB pilots are more on the junior side, and will not have WB super-seniority.
