That sounds like a serious re-plumbing job. The current system is so simple. How are you proposing to feed the counterlungs without introducing more dead-space? Minimum loop volume is important. Volume is lead.

That sounds fun. So you inflate the other wing and it all squashes up and you can't breath? How are you going to do a big diluent flush if you can't cross you arms and flatten both counterlungs in one grab? This is life expectancy stuff. How is the water trapping going to work if it is uphill to the exhale counterlung? How do you clear water from the bottom of the scrubber? Currently it is roll right, right shoulder down, butt up. How do you drain a counterlung? I've done it (after a rather silly error I'm not proud of).
For crying out loud. You never notice the counterlungs. It's that darn great breathing hose that clutters your front. The 'cluttered front' is a non-problem. It's not like you're clipping off gauges to your waist because the only things you need to see are hanging over your shoulders on cables.
The thing is too wide not too much at the front. I added a pocket on the waist and rate it a gain not clutter. As soon as you hang a couple of stages on it the counterlungs are tiny. Playing 'twinset mindset' isn't going to help because you're solving the wrong problems.
Try asking: Do you want access to the Oxygen? What about Semi-closed mode bailout? How do you connect a whip from a stage into the system? (You sure don't want to breath it OC.) In the event of CO2 build-up the usual report is that you can't afford the time to change to a regulator so what are you going to do? Fiddling with the harness or the counterlungs isn't tackling what the Inspiration problems really are.
Sorry. That turned into a rant.
