That said, you are quickly leaving the realm of UL packing.
I know in your introduction post you said you were coming from SUL packing
and wanting a bit more comfort so you were willing to go to possibly UL levels.

I would take a close look at Water Monkey's videos.
IMO, he is one of the most savvy UL hangers I know.
His gear is light weight and taylored to specific trips.
