Sean:
I assume you've been to Barnbougle more than once. If so, I wouldn't try to combine that trip with King Island. Play both of the King Island courses twice, and do play the nine-hoper in Currie as well -- either on your way in, or saving it for the windiest day, since it's fairly wide open and forgiving.
I personally don't think they're as good as Barnbougle and Lost Farm, but of course, I wouldn't.
If Tom and Bill Coore chime in I'll have the set.
I imagine this is as far as you'll get, but good luck with that.
