That is very interesting puzzle. I find one workaround by using intermediate plane object and load black and white image into as opacity texture. Plane is positioned between ball and light. So you can change opacity map design as well a position of plane between light and plane. 

Also you can use Area Light (and customize it for your task) or create Environment light image and load into Stager.
