A long while back I had made something just like this as a hammock pad - to be used inside the hammock, between hammock and hammocker.
It was layered like this, from top to bottom:
-1/16" packing ccf like you mentioned
-1/16" packing ccf
-1.6oz ripstop, uncoated
The 'pad' was 3'x5' and weighed 16oz. Heavy for what it was. Worked well in moderate weather. I sent it along with a friend who did half a thru-hike on the AT this last summer - he said it saved his butt on those cold nights. It was the only underinsulation he had.
Having learned a good bit more since then, I don't think I'd bother making another one. Here's my latest thought on what to build.
A synthetic Climashield UQ with a bottom sleeve to insert a layer(s) of insultex into (making it adaptable to expected temp. range). This should conform to the hammock properly, and maintain that air gap that Insultex needs to perform well. Worth a try, anyway.
