You could save a few lbs:

I use the same pack, Atmos 65. Love it.Cut the bottom internal flaps out, you don't need them (minimal weight savings anyway, just helps packing).

You could get by with a thinner sleeping bag. I've been fine with my WM 32*F bag down into temps in the hi teens.

Leave the footprint back. Not sure what the tent weighs, but if its over 3 lbs there are lighter options. Leave the daypack home, just empty the Atmos 65 and use that.
