This macro works as expected in batch mode if it is modified to use the
command recorder generated run("Merge Channels...", "...") call that
includes "gray=*None*" in the options string.

   setBatchMode(true);
   run("Duplicate...", "title=temp");
   run("Split Channels");
   run("Merge Channels...",
     "red=[temp (red)] green=[temp (green)] blue=[temp (blue)]
gray=*None*");
   setBatchMode("exit and display");
