"Doom Emacs" is, in essence, a set of Emacs Lisp files bundled together, 
configured so that they interact nicely and coherently.  For example, 
smartparens, which-key and magit are part of Doom Emacs, but can be used 
(and were developed) independently of Doom Emacs.  The same holds for all 
Emacs "distributions", for example Spacemacs or Emacs Prelude.

The Emacs Lisp files contained in these distributions are loaded by Emacs 
when it starts and change its look and feel.  What you run is "standard 
Emacs", but with a number of non-standard (that is, not distributed with 
Emacs) Emacs Lisp files.

That's of course possible.  It suffices to replace one's ~/.emacs.d 
directory with the ~/.emacs.d directory of an Emacs distribution (and to 
move the ~/.emacs file, if it exists, to another place).  Switching 
between several Emacs distributions can probably be achieved with symbolic 
links.
