Normal Map without using the Normal Map

 I'd like to create a filter that takes a heightfield as an input and has a Normal map as an intermediary step then does some further processing on the normal map.

I'd like to avoid running two consecutive scripts (1: to create the normal map, 2: to run the further processing).

Does anyone know if a FF node based approach that would create a normal map image from a heightfield?

Thanks in advance for any help
