I think I tried that and found 
that this didn't work either.

But I can see no way that the 
macro can modify an object {} 
passed to it in a variable, so 
that it becomes a blob component.

I.e.: One cannot do this (I think):


#declare Spike = cylinder { 0, y, 0.1 }

#declare Ball = sphere { <0, 0, 0>, 0.5 }

#macro InsertComp(Component, Strength, Position)

  object {
    Component
    strength Strength
    translate Position
  }

#end // macro InsertComp


blob {
  threshold 0.3
  InsertComp(Ball, 0.5, <0, 1, 0>)
  InsertComp(Spike, 0.3, <0, 1, 0>)
  pigment { color <1, 0, 0> }
}


Thank you for commenting btw.
