The only problem with that might be that your vapor barrier is on the outside of your insulation. Generally, you want it next to the hammock, so that the water vapor doesn't condense in your UQ.
In this situation, I think I would be more inclined to bring a breathable DWR UQ protector, and a space blanket to lay between the hammock and UQ. I don't know what the weight of the metalized 30D nylon is, but there might be a small weight difference.
Hope that helps,
