you have great ideas
but instead of null objects can't you use #if defined() syntax ?

I don't understand what a macro would help with in this situation.

When I want use something like null object in macro parameters I use
array instead of variable:

#macro SomethingWithPossibleNullObject(Object)
  #ifdef (Object[0])
    // Work with it
  #else
    // No object
  #end
#end

SomethingWithPossibleNullObject(array[1])  // Null object
SomethingWithPossibleNullObject(array[1] { sphere{<0, 0, 0>, 1 }) //
Work with sphere
