Placement of built in screen

I’d like to install a built in simulator screen from Carls Place or Gungho, but my walls have concrete footings (~8 in tall x 4.5 in wide). Would you use the screen layout in photo 2 or 3? I prefer photo 2 because it fills the entire width and it would be easy to anchor the screen to the wall at the bottom corners, but I’d need to build something at the bottom to safely stop a duffed shot. Photo 3 is more standard in that the screen meets the ground, but I don’t know how I would anchor the bottom screen corners to the concrete and I would need curtains to cover the dead space on the left and right of the screen. I’m hoping someone has faced a similar dilemma and could share their solution. Thank you in advance
