Not me, excepted for "external design" until I understand this name as:
a design which is external to something
quote

"Atomic Design 1 + Atomic Design 2" =is-a=> Design

"(Design as Atom) + (Another Design as Atom)" =is-a=> External Design
      ^------ Sibling Designs ---^

Good if the meaning of "atom" is a common pratice in engineering,
nonetheless, one uses also this word as in its physical meaning, so
instead of External Design, why not saying Molecular Design?

Moreover, as you say in you draft, atoms are raw material indeed, so,
something which doesn't have a design, more exactly its design doesn't
matter compared to its property; even more precisely, something which
can't potentially impair the understanding of a design.
So why speaking about "atomic designs" when the design isn't the point?
Like in microphysic, an atom or a particle doesn't have some properties,
these are the properties which "made" the atom or a particle. In a sense
"25Pf" do the capacitor, though you need a capacitor and not something
else with the same property.
Of course, it's a problem of limit, but why not sticks with only:
-atoms
-design as atom (black-boxed)
-molecular design (a design is by this way always molecular)
