I realize there are considerable individual differences, and I'm most definitely a cold sleeper, but with a 30* bag and a NeoAir I'd freeze in the Winds even with all my insulating clothing on inside the bag. I've regularly encountered temps well below 20* in the Rockies, particularly at and above timberline (which is where you are in most of the Winds). In 2009 they got plenty of snow (a foot in Titcomb Basin, per the rumor grapevine--possibly exaggerated) on Aug. 8 and 15, with clearing temps in the teens. If you are warm enough in such conditions with what you have, more power to you! A friend of mine, who was a NOLS instructor for several years and has recently written an off-trail guidebook to the Winds, always takes a 10* WM bag. I've been fine with my 20* Ultralight and an insulated air pad (POE) with a torso length piece of GG Nightlight.
I agree with MikeC! about ditching the Crocs. My camp shoes are Goose Feet down booties with silnylon overbooties (3.6 oz. total), and the main reason I have those (other than pure luxury) is that my trail runners tend to tear up the ground outside my tent door during my necessary multiple exits/entrances. I have tried Crocs in the past (in my boot days); not only were they heavy and bulky, but they were not stable enough on my feet for fording streams. I just ford in my trail runners, wring out the socks afterwards and walk them dry.
I rehydrate (mostly home-dehydrated) food in a freezer bag inside a cozy, and eat it out of the bag. For two persons this system would be quite feasible if you each have your own bag and cozy. This system saves a lot of dishwashing and saves the weight of those bowls. Or you could put 2 servings in the freezer bag and have only one bowl. I also drink out of my pot (toss in a tea bag after pouring off the hot water into the food bag). This last might not work so well for two, unless you happen to like exactly the same beverage! When I do use bowls (when taking my grandkids out), I use 3-cup Ziplock bowls with the rims cut off--0.6 oz. each. You could use smaller ones for cups.
As MikeC! also pointed out, pack covers will not keep your pack contents dry. There are a lot of dicey stream fords in the Winds (as you probably know, the USFS standard there is not to build a bridge unless the ford is unsafe for horses at low water), and the pack cover is useless if you slip and go in. Stuff sacks aren't waterproof, either. Either a pack liner or dry bags for your critical insulation would be a lot safer! If you want to use a pack cover anyway (I do because my pack is my pillow so I want a dry top surface), my ZPacks cuben pack cover is 1.0 oz.
Of course your base weights are already below mine, so take the above (except for waterproofing your gear) as nit-picking unless you really want to reduce your pack weight further!
IMHO, the Winds are close to the most beautiful place on earth, and I wish you the best of trips! I hope to get back there next summer!
