Don't over look the fact that you can attach a regular PLC to LinuxCNC via Modbus TCP or RTU and have the tool changer logic run in the external PLC. Classic Ladder is really handy, but if you have a complex tool changer, it is a lot easier to write and debug a PLC program in a hardware PLC rather than using CL. The software editor/debugger is simply a lot better than CL. Sure the hardware PLC has a cost, but so does your time. I've used the Siemens S7-1200s with LinuxCNC with great success. They have a built in Ethernet port that can run Modbus TCP and the comm between the PLC and LinuxCNC is very fast.
