you mean something like this:

\unprotect

\def\activedododotextmodediscretionary#1#2%
   {\convertargument#2\to\discretionarytoken
    \def\textmodediscretionary%
      {\getvalue{\strippedcsname\textmodediscretionary\string#1}}%
    \ifx\discretionarytoken\empty
      \ifx#1\nextnext % takes care of ||| and +++ and ......
        \prewordbreak\discretionary{\hbox{$#1$}}{}{\hbox{$#1$}}%
        \allowbreak\postwordbreak
        \def\nextnextnext{\afterassignment\egroup\let\next=}%
      \else
        \checkafterdiscretionary
        \bgroup
          \checkbeforediscretionary
	 \textmodediscretionary\nextnext
        \egroup
      \fi
    \else\expandafter\ifx\csname\@tmd@\discretionarytoken\endcsname\relax
      \checkafterdiscretionary
      \bgroup
        \checkbeforediscretionary
        \prewordbreak
        \discretionary{\hbox{#2}}{}{\hbox{#2}}%
        \allowbreak\postwordbreak
      \egroup
    \else
      \csname\@tmd@\discretionarytoken\endcsname
    \fi\fi
    \nextnextnext} % can be \egroup so \aftergroup\ignorespaces

\startlanguagespecifics[cz]

   \setvalue{\strippedcsname\textmodediscretionary\string|}%
     {\discretionary{-}{-}{-}}%

\stoplanguagespecifics

\setvalue{\strippedcsname\textmodediscretionary\string|}%
   {\prewordbreak\hbox{\compoundhyphen}\allowbreak\postwordbreak}

\protect

\starttext

\en \dorecurse{100}{test||}test \endgraf
\cz \dorecurse{100}{test||}test \endgraf

\stoptext


so, in principle it is possible but i need to make it a bit nicer; maybe tonight -)
