On a sidemounted Rebreather you have a big hose ( usualy a Ray one which is very extensible ) on exhale side which have IMHO quite the same action +/- than a exhale CL.

mmhmm, perhaps a very small exhale counterlung, like the dolphin :-)
you can test the expandable volume of the big hose, while breating... will never be more than a glas of beer (and I mean a small pint!)
