I'd second the idea of simply snapping the mesh hammock to the suspension underneath your Travel. I had a DD hammock before, and I think that something like the mesh hammock would readily fit into the snake skin. If you tie the straps into a small loop closest to the hammoc, you can just leave a biner on there (assuming you've stuck with its original suspension).
So far I've just hung my rider gear freely on the suspension, but I've been thinking about a set-up like this. It would work for a backpack as well.
