I agree with Charlie, as I also mentioned in detail in my post a page or so back.
IMO part of model railroading is making things work. Mounting a coupler with a large lateral swing on the lead car is a matter of obtaining a long shank coupler, drilling a hole in the car floor and securing with a screw.
Select a plastic coupler from the LHS parts bin, such as from a baby Madison car and snip off the excess detail from the rear.
Eyeball how far the coupler should extend, picking a good spot on the car floor for a mounting hole. Drill the coupler shank in the appropriate spot with a hole large enough to allow a #4 screw to pass through. Drill the car floor with a slightly smaller hole and attach the coupler with a short #4 wood screw. Some shims (washers) can be added between floor and coupler to attain the correct coupler height.
I know it is not the ideal of having every car work with every locomotive on every curve straight from the box, but it beats depriving yourself of the enjoyment of running a neat looking loco.
Doing a little problem solving and coming up with solutions to problems is an everyday requirement in the world of scale model railroading, and every once in a while that approach is needed in the 3-rail world. Making things work with a little ingenuity can be very rewarding.
