Morph multicurved surface voronoi cells with attractor points

Hi everyone!

I have created a voronoi geometry on a multi curved surface. My next step is move the initial cells in a way so i can loft the initial ones with the moved.

The moved cells (before being lofted with the initial ones) are distorted according to a set of attractor points. My aim is to create an obvious variation of the sizes of the lofted cells according to the attractors' distortion, and what i have so far is approximately the same size cells. 

The result of the size variation is not that obvious and I don't know what i should do differently..

If anyone has any idea, it would be very much appreciated!

Thanks a lot!
