I am afraid that such approach would not work, as the design of our framework relies on kendo.fx having simpler implementation (present in kendo.core) and a more complex one that handles the animations (in kendo.fx).
Something which I may suggest is to set the animation duration to zero, in certain cases (IE, for example).
All the best,
