If it were me and I was walking multiday in cold rain prone areas I'd drop the down puffy and houdini wind shirt. Keep the two fleeces and have another base layer.
You can rely on the outdry rain jacket, it's the only rain jacket I trust for multiday rain because it can't wet out. Used it in days of torrential NZ rain on several trips now. I like the hood coverage but the adjustment pull cords are terrible. Wish it was longer.
If the base layer becomes wet(due to sweat as can happen on a hard uphill hike in the rain) then it's good to have a spare. In theory they dry while you're walking but if your walking in wet, cold misty conditions then even the baselayer will struggle to dry quickly as the air is saturated. In the meantime without a spare your cold and damp. . Been there got the tshirt

I should mention my spare baselayer doubles as sleep wear plus final day returning to civilization on public transportation wear. It's nice when the bus driver and fellow passengers don't suspect your a hobo due to dirt and smell.

Rain pants are needed.(edit. Noted your bringing them).
Can wear the two fleeces together at camp in cold conditions. Can wear one fleece if needed in very cold conditions when walking or during early starts until you warm up.
I don't like down in wet conditions as if it becomes wet its useless and won't dry. Also if you buy a expensive ultra light puffy you tend to have to baby it to prevent it tearing, where as fleece is much more robust.
If it's cold and wet I like gore Tex lined shoes. Hotter weather I stick to faster drying and lighter trail runners.
