Understand that you are using a single-wall 2P tent weighing over 3# packed that saves some weight by using trekking poles for support, and due to excellent ventilation, manages condensation well for a single wall. But sounds like maybe you want something lighter without giving up the benefits of the tent.
If you go to tarps, as suggested here, things will be quite different. Maybe you should rent or borrow a tarp before investing.
If I were you, and wanted what it sounds like you want, I would call Henry and inquire if a 2P version of the Moment is in the offing and worth waiting for.
It would probably have a second door on the other side, like the Scarp, but would have the tautness, stability, simplicity and light single-wall weight of the Moment, substantially lighter than the Nemo. And condensation would be less of an issue due to the net walls both front and back.
