Honestly, it wouldn't hard to take a PSP and pull out the fishing kit, mirror, sparklite and tinder, and swap in the cash, light, and meds. Keep the safety pins and sewing needle in their vial, maybe add a couple of screws for glasses if needed, along with the buttons.
A lot of the individual items people have listed are items I have listed in the Urban EDC thread. However your idea of converting a Pocket Survival Pack into an urban survival kit is something I've considered this week. Since the Pocket Survival Pack includes a needle and thread, a thimble would seem more useful than some of the other items.
