The other thing you can do if the tight radius is causing problems is to make a "tongue" to mount your Kadees onto. You make it long enough to position the Kadees at the normal position, but the other end of the tongue mounts to the same screw as your trucks. The kadee will act like a talgo (truck mounted) coupler when going around tight radius curves, but it won't put the side force that leads to derailments when trying to back up the way truck mounted couplers do.
