Sure the wiring is simple enough, you figure out the math input, and build a blend space using matched animations. With the math figured out you could then add the blend space in the animgraph make the scale pin visible and tie in your procedural input.
As well
Since a blend space is nothing more that a 1 or 2 dimensional array you can change the animations based on high and low extremes by adding it as a percentage point with in the graph. (obviously just changing the speed would look strange;) )
