Guess in that case it might be easier to spend time in Bombay first and then use that as a positioning trip to CMB or Lahore (two of the cheapest places to pick up a DONE4 in) and pick up a cheap DONE4 from there. Something like -
CMB/LHE - HKG-BKK-SIN-NRT-SYD-LAX-DFW-PDX-DFW-LHR-HEL-LHR-DXB-LHR-BOM-CMB/LHE (The last one being a surface sector to pick up another DONE4 - I hear these are addictive :P )
