How to Implement Weight-Blend Layers with an Automask Landscape Material

Hello, I have a question in regards to paint-layers for an automasked material. I would like to have a landscape mat that has both methods. Similar to the kite demo, though it doesn’t need to be so complex, just a slope and height blend, with multiple paint layers in addition to it.
Anyone know of any methods to go about doing so? Any information would be greatly appreciated!
