I've looked at a decent amount of his stuff (OP - on the phone).
>Gen 6 and the "sons of god"
Yeah, the "godly line of Seth" interpretation comes from Blessed Augustine, before that I think there were more Church Fathers who interacted with the Enochic viewpoint. Throughout the OT Scriptures the term "sons of god" (beney elohim) is a technical term for the high ranking angels of the Celestial Hierarchy. This stuff is important to know when refuting pseudo-academic atheists who say that the Yahwists were polytheists.
>Trinity in Genesis 1
Heiser denies it because it would be anachronistic for the writer to have known about the Trinity, and it is more likely to be God addressing the Divine Council. However, taking a philosophical/theological view - rather than a historical one - we understand that God only has councils of gods and men because He Himself is an inherently communal Being, being three Persons as One.
>Babel and the Watchers
Some of his most important work IMO.

Given that Samuel's ghost is called an elohim I find that pretty likely. A ghost and God are not even close to being ontologically comparable.
