Then there is the modification (http://www.dsprelated.com/showmessage/80739/2.php, Andor's post) to subtract the moving average from the _current_ sample (instead of the one corresponding to the middle of the moving average filter) but this supposedly makes the filter minimal-phase instead of linear-phase so it is still a no go (at least AFAICT from my limited knowledge).
Certain high theoreticians have surmised that the minimum phase version could be better. So, at least at high sample rates (88kHz+) you could go with that design as well, and at least in theory do it even better than with the linear phase, more complex design.
