By now you understand that unless you can bring Magnepans out into the room at least 3' you'll be missing most of what they do so well. My listening room is close in size to yours. I've had MMGs , then .7's, and now LRS+. I prefer the LRS+. Its size scales better and for whatever reasons I find the LRS+ easier to position. Mine are about 5' from the front wall I think the LRS+ lives up to all the hype and has earned all its positive reviews. Break-in time was around 300 hours for me. The bass response of the LRS+ is surprisingly robust.
If I were in your situation I'd likely be looking at speakers like Larsen, and/or Ohm. I've had both and while both brands have their charms, for my wife and me Magnepans win the day.
Hope this helps. Best of luck on your journey.
