It makes sense to reduce B-format to stereo.

But the target is important, if you aim at headphones, there are decoders that 
create an binaural signal. If normal stereo-systems are the target, you will 
do a decoding similar to any ambisonics setup but only use two speakers in the 
correct stereo positions and decode to file...

The headphone-version gives more of the ambisonics feeling, but the normal 
stereo signal also benefits from the recording done in ambisonics.

Have fun,

Arnold
