We used to put your principal in place hunting geese on thin ice. We would take a light aluminum boat and push it across the ice till we would drop a foot through, then we hopped in the boat and used shovels to push across the ice from there. By spreading out weight this way we got across stuff we shouldn't have. I don't recommend this method if you can't push off bottom if the whole boat goes through its really hard to get back on top of the ice without a strong push.
Anyway I'm an engineer so I followed your reasoning. I'm just not sure about the fracture mechanics that start the ice failing. With all the internal stresses due to water expanding as it freezes when you apply a perpendicular force to this mix its hard to say how much it will take to cause the columnar loading to buckle. But then again this is more likely a plate theory. But I guess I could work on that the next time the fish won't bite. Later J
