Seating configuration on CX 146 to Hong Kong A330-300

[kinkacruiser]

I booked the last 2 business class seats together on this flight ...not the best position (11 D&G with the toilets in front). Any chance there could be a swap organised on board to a better spot? I note that single seats are booked in the middle twin seat section. Is there something wrong with the window seats that singles choose to sit where a couple would be better placed?

Thanks in advance.
