curious as to where this is going.
I don't have any advice for you but I kinda wonder where this is going to end up. I admire innovation.
I thought that the advantage of the open bridge Chrysalis design was that it was possible to use sleeping pads right on top of the hammock. Unlike other hammock designs,you don't have the hammock fabric wrapping around you trapping moisture and compressing the insulation of the bag. Have you tried it with just a closed cell foam pad or two? Other than some condensation I've haven't had any problems down to below 0 C.
