3) Start a DONE4 there, go to London. Continue the rest of my travels next spring. Arrive back from the East at KHI. Fly KHI-ISB, and then use the return on my coach fare.

The advantages to this is that since I'm westbound, I won't have to burn a segment to get out of the country. The downside is that I can't start and end in the same city, but KHI-ISB is cheap. The total cost works out to be about the same, I believe (since I want to fly AA and there is no AA # going to CMB).

Is there something I'm missing? I haven't heard much about ex-Pakistan DONEs.
