If you can live with a muddle of plain, latex and context, then
consider the soul.sty package (available on CTAN).  I've included an

%--------------------------------------------------
\input miniltx
\input soul.sty

\sodef\SO{}{.08em}{.4em}{1em}%
\setuplabeltext[chapter=\SO{CHAPTER} ]
\def\ChapterTitle#1#2{%
  \vbox{
    \hbox{\midaligned{#1}}

\setuphead
  [chapter]
  [command=\ChapterTitle,
   page=right]

\setupbodyfont[cmr,10pt]

\starttext
