It would be cool to make a new slot D-23 and actually not very difficult considering the external 3d work is identical to the D-22. The flight characteristics of the D-22 were not all that far off from the D-23. I think all that distinguished them was the factories they were built at.

I think the D-10&22 in game which use the early Curtiss paddle blade propeller. It should be a little better than D-27 if equipped with hamilton or late Curtiss products.
