Fellow MD trying to help with engineered solutions.

Perhaps check this out as well; someone used a common valve from a hardware store to titrate pressures up and down: https://www.youtube.com/watch?v=eSVbwWANqRI&feature=youtu.be.

I've been thinking about how we might increase ventilation to one part of the circuit if the pCO2 drops too badly--any thoughts there?

Thank you for pointing this out! I’m trying work out how to get in touch with this guy, unfortunately he has turned off all comments.

I’m not sure I understand your question: do you mean if the one patient is getting hyperventilated? My suggestion is to set the pressure settings to ventilate the poorly compliant compliant lung, then use the flow restrictor to compensate on the more compliant lung.
