If the new lie-flat J seats are the same as that of the new CX J seat I could live with the tradeoff of not having any F and having the new J seat on the 763 which would make the Hawaii runs from DFW/ORD a lot nicer, especially on the red-eye coming back. But if they are only going to do half of the 763 fleet and keep Hawaii with the present config this is not only going to *stink* but will cause operational nightmares as equipment swaps for mx and delay reasons will become more difficult. Do the whole 763 fleet and give yourself the flexibility. It's only money.
