Wwings, you mention two interesting ideas.
Firstly, it does seem feasible for the A330s to based purely on the leisure routes after the first few 787s have arrived. However this is heavily dependant on what they do with the 787s, I believe they initially wanted to have an LHR plus a leisure config but after their A330 experience, maybe it would be a simpler and cheaper option to just separate the two aircraft. Also the 787 carries similar pax numbers to the A333 but quite a bit more cargo, making it more suitable for the far east.
