I don't think Hal should be a doofus/comic relief. IMO, Hal reminded me of Guy in the early JL issues, and the in the two New 52 JL animated features.
Playing the fool for Batman is a Guy-thing which made Hal punching Batman in front of Guy during Rebirth funny.
Hal seemed more like early Kyle in the live action GL film.
It seems like folks can't settle on a basic personality for Hal in their attempts to push him.
