Looking at Google Earth exiting 4R at Kilo you would cross the hold line for 4L and 8L before you cross the hold line for 4R. So there’s really no space on Kilo between the runways. I would think if ATC wanted you to exit at Kilo they would have to include a clearance to cross 4L. We just always rolled to the end since most of the time we were going to the Diamond Head ramp.
