In our operation if we were flying the 25R approach SE then we would demand the company EOSID which would take us staright out to 7 miles on the ILS DME and then turn left. We would not consider doing the standard missed approach. If we were in the G/A before the 3 DME fix then the same would apply. However if we were pointing to the high ground then lost a donk and were concerned about terrain clearance (overweight landing due immediate return for example) then it would be immediate radar vectors away from the high ground! In practice I think you'll find that HKG ATC would assist with a clearance in such a way since there have been some windshear go-arounds off this approach where people have not wanted to turn back into the shear area.
