In the real planes it is possible to "reverse" without props that have reverse pitch. It takes a multi-engine plane and the toe brakes to do.
For example on the B-17... To reverse, all you do is hold the right brake and throttle up #4. This causes the plane to pivot around the right wheel with the right wing moving forward and the left wing (and fuselage) moving backward. After a tad of that, close throttle on #4 and then you then hold the left brake and bring up #1. The plane pivots around the left wheel with the left wing moving forward and the right wing (and fuselage) moving backwards.
Net result after a few of these is the plane waddles backwards. It does require a plane with engines outboard of the wheels though. The further outboard, the more effective the maneuver, less throttle, etc.
