I never understood why so many people out there have Scope screens then sit so far away from them or don't have them fill their peripheral vision. Go big or go home I say (or go out to the cinema and leave home!)
Seating distance is key, more so than physical size. Even with a 10ft wide scope screen, if you have the first row at say 2 x to 2.4 times the screen height (or whatever your preference is), you will get a visually immersive experience, so you don't need a wider room. However, scale can make a difference on how you feel about your physical screen size, so that probably won't appeal to you. Like you say, why have a big screen and sit so far back from it.
If scale doesn't bother you, you could run a 10ft wide CIH + IMAX set up - semi permanently mask your 16:9 screen to 2.40 to run it CIH and move your seating closer so that the screen height to seating distance is the same as you have now for your 16:9 screen, so that way, visually 16:9 looks the same size on your retina as it does now, but scope movies are the same height but wider and more immersive as designed and intended. Now, when you watch an aspect changing movie, remove the top and bottom masking and you will see the height changes for those few scenes that have it and will be closer to the IMAX experience - there should be a difference between IMAX and 16:9 presentations.
Of course, changing to a set up like that not only means moving the seating, but the surround speakers as well.
