Good point, BuzzBox.
I had considered that option also, and reckon it would shave about another 1-2 mins off the time to return. Even though the 20 kts TW is outside limits, I estimate you would need about 3000m of runway to land a 767, which is less than the majority of airports we operate from.
I was tending to shy away from this option, in the given circumstances, because:
1. At heavy weights, I'm not sure that brake energy limits wouldn't be exceeded.
2. You may be compounding the problem with a brake fire.
Happy to be convinced otherwise
