I think not. There is -E 0,0,1 to reduce it to mono by averaging, but
the manual page (which it is worth reading!) says that internally
transcode supports a maximum of stereo and mixed multi-channel input
down to stereo before further processing.
In any case you really want a tool that does not decode and recompress
the stream, but simply demuxes the streams, discards two channels and
remuxes them. I don't know of such a tool - the closest I see are the
are the example utilities provided with libavifile (avimerge, avicat
and so on); you could probably write a small program to achieve what
you want by taking one of those and modifying it.
