Under 10 lbs, but with a framed pack and without a tarp. Might be tough. A Tarptent is probably the way to go shelter-wise if your friend doesn't want to tarp it, but there's really no need for a framed pack at weights like that. Even on a through-hike. Just be sure to get a pack / sleeping pad combo that'll transfer a bit of weight to the hips and you'll be good to go.
I absolutely agree about gear swap. Granted, if your friend is in a hurry to get set up, that could be a bit inconvenient, but he should be able to score a couple items there.
I'd recommend something like this:
Six Moon Designs Swift - 18 oz w/ hipbelt (which he'll want) - $140
(there are lighter packs, but this one's big and durable which makes it more versatile, and worth the weight penalty in my opinion)
Trash compactor bag liner - 2 oz - free
Tarptent Squall 2 / Cloudburst 2 - $$230/$260 - 34 oz / 39 oz
(I recommend getting a 2 person shelter so he can take someone else if desired. The model depends on whether or not he uses trekking poles)
JRB Sierra Sniveller - $250 - 24 oz
Neoair (Small) - $105 - 9 oz
Warm sleeping socks (Hey... I carry 'em) - free - 4 oz
Montbell Thermawrap - 8.8 oz - $150
OR Ninjaclava (Super versatile, works great as hat or balaclava) - 2 oz - $28
OR liner gloves - 1.5 oz - ~$25
Golite Ether windshirt - 4 oz - $80
or, depending on conditions:
North Face Triumph Anorak - 6 oz - $180
Extra socks - 2-3 oz - probably free
MYOG Alcohol Stove - 1 oz - free
Snowpeak 600 Mug - 2.8 oz - $28
MYOG Windscreen - 1 oz - free
Mini Bic - .5 oz - free
Light spoon - .5 oz - < $5
4-8 oz bottle to hold alcohol - .5 oz - free
Katadyn Hiker Pro filter - 9 oz (after removing some accessories) - $80
(sue me, I like a filter when I'm not fastpacking. The taste is way better)
Platypus 2 liter hydration pack - 3.5 - $18
Platypus 1 liter bottle - 1.5 - $11
Black Diamond Gizmo headlamp - 2 oz w/ batteries - $18
Brunton Base Plate 810g compass - 1.5 oz - $18
Ziploc w/ sunscreen, bug spray, first aid, duct tape, cottonball firestarters, extra lighter or firesteel, etc - 5 oz - cheap or free
Map - < .5 oz - possibly free
Leatherman Squirt PS4 - 2 oz - $28
Dyneema Bear Rope - 1.5 oz - $20 (totally stolen from Kyle)
Total = 9 lbs, 4 oz and around $1350 for a super comfortable kit.
This is off the top of my head, but it doesn't appear to be missing anything. If he buys some of this stuff used, he'll probably spend well under $1,000. This kit also leaves him some space for a camera and a luxury item or two if he really wants one, while still staying under a 10 lbs baseweight.
Edit: Forgot a knife and bear line.
