What about if they designed and optimized an SCT with a 2" diagonal for since eypieces, and a shorter 1.25" diagonal for binoviewers. This would reduce the increase in focal length for the binoviewer.

P.S. I can clearly see that if I ever get an SCT, my binoviewer will not work as well as it does on my 17.5" f4.1 Newtonian Dob.

An SCT could be designed so that the nominal location for the focus is farther outside the back end. But to do this does require a somewhat larger secondary mirror.
