You would first have to define the reverse to avoid misunderstanding.

        --noreplace (-n)
               Skips  the packages specified on the command-line that 
have already been installed.

Reverse: Install packages that are not already installed

- This is what Portage does by default

Reverse: Skips packages that are not installed

- Makes no sense with installation actions. Is this what you mean?

pena betelgeuse # emerge --depclean foobar
 >>> No packages selected for removal by depclean
