We had something similar on our IP 27, but it was simply fabric. It was attached to the hatch slide and then with the slide open all the way, it had one piece of screening that ran from the slide lid to the corner where the lide would be closed. At this point there was a dowel rod inserted into the fabric and from there it simply hung down to the bottom where another dowel rod was. To come and go was easy, you simply lifted the dowel rods and opened it up. There was no need to slide the hatch as it remained in the open position. The top screen fabric was wide enough to over lap a few inches on the hatch slides. Then the vertical piece fit into the companion way board slots. It worked very well, and my wife, Radeen, wants me to make one for our IP 35. It would be easy.
Your idea sounds good, except the hatch lid needs to be closed and move with every coming and going. Maybe that would be ok as well.
For us now, we use a simple solid piece of plexi glass that fits into the door area. We slide this in place then slide the hatch closed. To come and go, this too requires the lid to be slid open then the plastic lifted out and turned. So it is not as easy as cloth or screening.
The best set up has to be doors, but they are expensive.
I would like to see your idea in use, it sounds like a great idea as well. I have never seen this.
