Can the 1600kg pack be upgraded simply to the bigger one
This is on a AWD version, so the diff should be okay anyway.
Not really, different animals entirely. If you now want 2300 kg capability, I would suggest replacing the 1600kg unit with a Hayman Reese unit - which is 2300kg, and flogging the old one on eBay. I am assuming you have the genuine Ford wiring harness, which you would obviously want to keep.
Only issue you will have is the HR bar does not have a facility, as standard, for the trailer socket to mount to like the Ford bar - your fitter will have to fit one for you.
