best checkpoint-friendly carry-on backpack that fits under seat

I have been on a quest to find the best backpack for my business travels. One that is . . .

• checkpoint friendly
• carry-on size (preferably 22" x 14" x 9" or under)
• distributes weight well so I can wear it while riding my motorcycle

and has enough capacity to carry . . .

• 15.6" notebook (~7 lbs.)
• 10" tablet
• projector (10.2" x 7.4" x 2.8")
• charger x3 (notebook, tablet, phone) and cables x 5 (various types and lengths)
• wireless mouse, compact digital camera, belkin mini surge protector
• flash drives x 3
• hygiene (toothbrush, paste, deodorant, lip balm, etc.)
• clothing for 3-5 days (I use the bundle method to pack, so it takes up less space)

I've looked at some tactical bags like the 5.11 Rush 24; and I've looked at some daypacks like the North Face Overhaul 40. Unfortunately, none of these seem to fit the bill.

If I could fit all of this in one carry-on size bag, I'd be ecstatic. Any help or suggestions would be greatly appreciated. Thanks!
