This almost describes my current project which is retrofitting a round column mill using ethercat drives and I/O modules, Safety relay, flood and mist coolant, VFD spindle control using RS485, optical spindle encoder, separate HMI enclosure. I thought of it as being a reference build similar to your idea. It has pneumatics for the mist, mains switching for coolant pump but no lubrication system, pressure sensors or level sensors. It's really way over the top for the hardware being used but I have certainly learnt a lot!
