That's called a Tornado. But let's look at performance. If you peel away some of Tiki's 700 lbs and add a more powerful rig, then what? You have the approximate perfomance of an H16, on a reach, enhanced by the improved downwind performance of a modern spinnaker. Plus the utility of an occasional overnight.

Don't let the "cabin" throw you. I'm just thinking of something with about as much room as a pup tent.
