Yes, I think this would be possible, in principle - depending on the 
codec(s) that you plan to use.  (Some types of stream - e.g., MPEG-4 
and H.264 video - work by passing codec-specific 'configuration' 
information to the decoder before the stream starts.  You would 
probably not be able to change the bit rates of such streams 
on-the-fly.  For other codecs, however - e.g., MPEG-1 or 2 - you 
could probably get away with doing this.
