i took a quick look at it; the problem is that it will mess up other things; the period in fullsectionnumber is a placeholder that will be replaced later on; the actual code where things happen in \doseparatednumber and it's not that easy to hook level dependent separators in there 

(i will reimplement sectionnumbering some day soon due to some other pending issues) 

anyhow, here's another approach: 

\starttext

\unexpanded\def\seplist#1%
  {\ifx\sepnumber\undefined\def\sepnumber{0}\fi
   \increment\sepnumber
   \getfromcommacommand[#1][\sepnumber]%
   \ifx\commalistelement\empty
     \getcommalistsize[#1]%
     \def\sepnumber{\number\commalistsize}%
     \getfromcommacommand[#1][\sepnumber]%
   \fi
   \commalistelement}

% \setuphead[section]   [separator=\seplist{?,!,*}]
% \setuphead[subsection][separator=\seplist{??,!!,**}]

\let\spr\seplist % quick hack 

% \setuphead[section]   [separator={?,!,*}]
% \setuphead[subsection][separator={??,!!,**}]

\setupheads[separator={A,B,C,D,E,F}]
