Sure it looks do-able on paper..and it sells jets...but not a viable option for Hawaii. Not by those numbers. Wet footprint. Contingency planning for S/E drift down or loss of cabin pressure at ETP would be a no-go for any prudent pilot.
I've been making the California-Hawaii run since 1990 in various types of bizjets...some more capable than others but would never launch with a wet footprint.
Having said that I have seen, through the years, Lear 36, Sabreliner, WW2 and HS 125 on the ramps in Hawaii...this is a 2200nm crossing with no diversion alternative but to turn back. Throw caution to the wind and anything is possible I suppose.
