I think you will only need 2 plants for that amount of space.
The whole point of a ScrOG is that all the buds are growing at the same level. I see how by bending the screen at an angle will give a greater length, but in reality it will not work. The stems growing in the middle will be fastest, and the branches which reach to the edges are slowest because they have more distance to travel. Also the main point with this method is to have the light spread out evenly amoung bud sites.
Everything else is great though
