Deform Target Surface with Intensity Control

I have a polysurface that I wiould like to deform with the geometry of another similar suface but be able to control/morph the intensity of the source surface…how would that be best done.
I just post this in the grasshopper forum for another concept but its not the same topic
Imagine the pattern here deforming the larger object but controlling the effect of the detail in realtime using a slider…is that type of thing possible? (Purely in Rhino)

You will have to create a definition in gh and then publish the sliders to a remote panel. Or use human ui.
