No, but there is a solution.  I have a solution which may be
derived from the set of macros that you're thinking of.

You need the following style file, `relative_sizes.sty':

% Subject: Relative font sizing in LaTeX
% Keywords: LaTeX, font sizing
% 
% One continual annoyance to me is that LaTeX does absolute font sizing,
% and so if you have some \newcommand that uses the sizing commands to
% achieve some graphic effect, you'll discover that your chapter heads
% and footnotes and such are pretty screwed up [in a recent case, I
% wanted a fake small-caps-san-serif font, and so I used {\small\sf
% NOWISTHETIME}, which did just what I wanted in the running text, but
% was an unmitigated disaster in the chapter heads].  I think that the
% following is a significant improvement: \smaller and \larger changes
% the point size *relatively* by one slot, and so I made my definition:
% {\smaller\sf NOWISTHETIME}, and it all magically works.

% Modified by George V. Reilly (gvr@cs.brown.edu) to handle non-Roman font
% families correctly, so that this really does work usefully in titles, etc.

---------------------

Now add the following two lines to your preamble:

	\def\pCHORUS/MiX{C{\smaller\smaller HORUS}/{\smaller MiX}}
	\def\CHORUS/MiX{\protect\pCHORUS/MiX}

and you can now use \CHORUS/MiX like this:

	\section{Is \CHORUS/MiX\ the way to go?}

	And now we discuss \CHORUS/MiX, a wonderful new thing indeed.

The two-step definition of \CHORUS/MiX using \protect is
necessary if you want it to work in commands like \section.
