next time post with less typos -) 

anyway, here is a working solution: 

\unprotect

\def\setupframed
  {\dodoubleempty\dosetupframed}

\def\dosetupframed
  {\ifsecondargument
     \@EA\dodoublesetupframed
   \else
     \@EA\dosinglesetupframed
   \fi}

\def\dosinglesetupframed[#1][#2]%
  {\getparameters[\??oi][#1]}

\def\dodoublesetupframed[#1][#2]%
  {\bgroup
   \let\dodoubleempty\empty
   \def\doframed[##1]{\gdef\globalredefinedframed{\dodoubleempty\doframed[##1,#2]}}%
   \getvalue{#1}%
   \egroup
   \letvalue{#1}\globalredefinedframed}

\protect

keep in mind that some 100 setups of the same instance may lead to rather big definitions 

\setupcolors[state=start]

\starttext
\setupframed[framecolor=yellow]          \framed{A}
\defineframed[myframed][framecolor=blue] \myframed{B}
\setupframed[myframed][framecolor=red]    \myframed{C}
\stoptext

i need to think about adding this, since it may break other things (i will run it for a while) 

you can add such patches to cont-loc.tex which is not distributed but read at runtime
