I intend to install a spring-loaded touch plate at a fixed location so the machine goes automatically to that position after the tool change, apply the offset and resume milling.

Maybe I'm just lazy, but I want a moveable touch plate. I'll place the touch plate on top of the material to be machine, jog the bit to directly over the touch plate, then run a macro to determine the new Z axis zero for this bit.
Auto tool changers are way cool. The high school has an 8 tool machine. It keeps a tool length offset table instead of a touch plate. The machine's name: "Sweet Vickie". It's true.
