The Might Deck model... I always thought a convertible top on a 4-door Kick, Tracker or Vitara would be interesting. Have the convertible top start 6-8" behind the front windshield frame, and between the top body seams, all the way back to a foot or so before the back door seam. Maybe a cross brace or two between the front and back doors to retain some rigidity in the event of a roll over. It would be slightly more secure than a rag top, but you could still have the open air feel when you removed it.
