My advice would be to make a "test" hammock from some cheap nylon fabric, to see if you can get comfy in it, before going to far with your home made system.
Mostly because the good home made versions are similar in comfort to Speer-type hammocks, and I consider the Hennessys to be more comfortable than Speers, and more bug-proof. If you couldn't get your Hennessy to be comfortable enough, It's unlikely you'll get your home made ones any better.
I have 3 Hennessys, one Speer and 8 home mades. The roomy Safari Deluxe Hennessy is always my preferred backpacking hammock, although my wife, Anna, likes the Speer better, because of the top entry. She still gets claustrophobia in it, especially in bear country.
