An interesting and awesome technique! Sadly it's limited by the original geometry's indices/layout. In real rolling shutter a point could be captured multiple times on a single frame, which I don't think can occur here
It looks awesome and I am very grateful for having such a knowledge for free. However, there are plenty of ways of resolving that same effect with some little Kinefx effort. Why not just making a procedural rig of those cubes? By the way, I haven't tried yet but I think of with a more complex mesh it will not look so nice, just guessing.
