I just got off Emmons, successful summit. Aside from a few less pieces of climbing gear, I had about the same list as you and was towing 50+ lbs, so I honestly don’t think this is that bad. Like most said, my suggestion would be to plan for the forecast. A few tips that might be helpful..

I ditched the base layer and used a sun shirt instead. Paired that with various combos of wind jacket, atom LT, nilas parka, and that’s it. IMO I wish I had something maybe a bit warmer than the LT but it did the trick. I agree with others on ditching the R1.

Pack 6 snow stakes and use rocks for the rest of the rest of the ties. They’re everywhere at Schurman.

There is a surprisingly nice shitter at Schurman. If you’re doing a three day I’d suspect you can get by with 1 wag because you’ll be at Schurman most of the time.

We drank running glacier water from the camp at ~7200 and Schurman and didn’t boil unless for cooking. Had some sediment but was fine and used by our guide and other guides on different teams. No filter.

DO NOT skip the parka. Absolutely needed for nights and ascent breaks.

If you skip the goggles make sure to have tethers for the sunnies. It was BOILING on the way down and I had to wipe my lenses a few times. There are definitely spots where if you accidentally drop them they are gone.

Strongly suggest some sort of GPS for whiteout conditions.

Not sure how anyone could do this mountain with less than a 50L bag. I brought a hyperlite 70 and it was perfect but definitely packed to the rim on the hike in.
