You should be able to zoom your image out to 106". Obviously, it will be bigger than your 92" screen, but you'll be able to see the effect of the larger image size on PQ.
My guess is that it will have a negligible impact. Your resolution won't change, but each individual pixel will get a little bigger and less bright. The one thing I would look for is an increase in Screen Door Effect, (SDE). If you can see the pixel structure at 12' viewing distance on the 92", it will get worse as you increase the image size. With a 106" screen, you will be getting close to the 1.5x screen width location that is the minimum recommended seating distance.
