REI half dome 2 checks most of your boxes but is a bit heavy at 5 lbs. I find it to be excellent as a tent, but prefer a hammock when there are trees. However, there is no such thing as a two person hammock that works for overnight, so the tent can be an advantage. 2 1/2 lb per person is not too bad. Full retail about $180, I bought mine for 50 at an REI garage sale, almost new and very little used, and no damage to tent fly or poles.
