That would be a pretty awesome sight! Alot of people don't realize what great predators the mink are. They're actually very efficient at killing and eating muskrats.
I've never had one come to a call, but, I did nearly get attacked by a "swarm" of about five mink once. I was a teenager at the time. It was the first summer I was allowed to take the boat out by myself. I had taken the boat to a remote bay near Hessle/Cedarville MI. There was a sand bottom and I was out of the boat swimming and gathering freshwater clams for fishing bait. I was anchored in about seven feet of water and probably twenty feet from the boat when I heard this awful chattering noise coming from towards the shore. I looked and saw these dark little heads sticking out of the water and weaving back and forth in a single file line through the water towards me. I never moved so fast through the water! The boat was a little fourteen foot aluminum v-haul with an outboard motor. I thought I would never get climbed up into that boat, but I did, and fairly quickly. As soon as I made it into the boat those mink caught up with me and started swimming circles around the boat like sharks. If I didn't do something quick they were going to find their way into the boat. I cranked up the motor and away they went.
I never have heard a good explanation for their behavior, nor have I heard of anyone witnessing any simular behavior.
Well sorry for rambling. I enjoyed your mink experience and thought you might enjoy mine.
