Does it possible to have this?

Say simple 5 red volumes
one complex green volume
Replace these 5 "cubes" by the complex green volume so 5 green complex volumes
(cubes can be different)

the same but but with a family of volumes?
here familly= a complex green volume + one orange cone
so result will be if not randomly
complex volume, cone, complex volume, cone, complex volume
or randomly
maybe cone, cone, complex volume, cone, cone
