Voronoi cell based of heightmap

It would be neat if the cell height of the Voronoi device’s Cell generation could be based on the values of a heightmap. Multiple way to implement, either taking the average height of each cell, taking the height at each point of the Voronoi’s point generation or the highest/lowest value of each cell. The application would be for example to create basalt pillars or an alternative approach for terraces (as you can blend them in using the Min or Max methods from the combiner for example).
