BA's B772 and B77W have the same rear galley config as the A35K so they should know if that config works or not. Is the problem that the A35K is more narrow at the back and the physical space between the galley units are too narrow compared to the B777?
Also interesting that the B788/789/78X are quite low-density (214/216/256 seats) while they packed in 331 seats in the A35K and they all fly the same routes.
Although the galley layout maybe similar to the 77E/W, they aren’t the same.
The 777 works in that layout because there are two levels of canisters. Whereas the 35K only has a single level of them above the ovens, as demonstrated in the below images.

BA 777-300 Galley (Double stacked canisters slightly cut off in this picture).
The 77E/W also has a larger monument aft of the last row of seats which holds more canisters and carts than the 35K monument aft of the seats.
If my memory serves me correctly, (on that aft monument), the 77W holds 12 half carts, 77E 10 half carts, but the 35K only holds 6 half carts.
Although the 35K is narrower than the 777, it doesn’t make a difference in the aft galley given how Airbus & Safran have optimised the space.
Looking at the seat map, is that tiny little rear galley supposed to service the entire Economy and Premium Economy cabin? 275 passengers? What were the cabin designers smoking! Even just servicing the Economy section would be tricky. Something more akin to Virgins would work better. Interim option would be to install some more galley space around rows 40-43
Correct - the aft galley caters for both Y & Y+, with a number of items also being held in the mid galley due to a lack of space.
