Passenger car truck upgrade

I am building a 4X8 layout in C&NW scheme. With this being this small, the radius of most of the turns is too tight to use the 85’ passenger cars and have them look right. Because of this, I have picked up a number of the Life Like “toy train” cars that appear to be about a scale 60’ long and plan to re-paint them in C&NW colors. These cars look much better going around my layout and going through all my #4 turnouts. The biggest problem that I have with them is their trucks - primarily the coupler pockets. I can not upgrade these cars from horn hook to knuckle couplers! Does anyone know of a replacement passenger truck set that will accept the better couplers and be able to be mounted under these cars? I have tried the Athern units, and they would not fit the cars correctly with out a lot of modification to the frame.

Any and all help would be appreciated.
