A 2P DCF shelter sounds bulky.
I’m guessing you have a WI Blazer bear can from the listed weight. That’s a moderately large can.
I’m guessing you will not comfortably fit all of that into a 40 liter pack although everyone measures their pack volumes differently. That sounds like a pretty full ULA Circuit to me (I see your other thread) which is much larger than any 40 liter pack I have ever carried. I think the Circuit sounds like a reasonable choice. I haven’t used a Waymark so I cannot speak to that.
You can try to find a box that has 40 liters of capacity and see how that goes. Also you could take all your gear to REI and try stuffing it all into a pack or two.
Unsolicited derail: Most of your First Aid and Personal Care sounds like a lot of weight (and therefore bulk). Repackaging your sunscreen, for example, would save nearly a half-pound. There are other places you can save some weight (and again, bulk) if you want to talk about those.
