I would stay with how the system is shown here on the site. Everything connects somehow with another and there is a reason for every little detail. I was very imporessed when I installed it in the first room in our house. We started with the plain harrison look in the and upgraded to greenwood for the living and bed rooms. One thing that comes to mind why you would not want the grooves horizontally because they would be intercepted by the vertical separators between the boards. If you end up doing it, do post photos please so we can see how it ended up looking. You never know!
