There is nothing modular about
the Apollo spacecraft. The CSM is a matched pair always and forever.

Wasn't there some non-trivial thoughts about a light-weight mini-SM for
use with Earth-orbit missions like Skylab?

There was. But substituting a SM late in the game isn't the same as
designing a modular system.

The OP suggested that Apollo was a system where you only hauled along
what you needed for a specific mission, leaving the remainder at home.
That is in fact,a modular system, but it's not how Apollo was
designed.
