If we have a player like Hakimi who is an out and out attacking Right wing back then any RCB wont be expected to leave their position and join in the attack I wouldnt have thought, one of their primary roles is to cover the Wing backs attacking.
When CHO played wing back against Burnley, the opener came from azpi overlapping CHO, there is definitely flexibility in the formation to allow the right centre back to push forward. Even under conte, Azpi was stepping into midfield and putting in dangerous crosses.
In the youth team, James played right centre back, with Dujon Sterling at right wing back and it worked out well.
I dont think it is a priority area to strengthen, but I also dont think it is a bad thing for James, he is quality, and he will play, and personally i think he isnt that suited to wing back anyway, because he isnt great taking on his man 1v1, by the looks of it, Tuchel feels the same, hence the Traore and Hakimi links.
Azpi will be the one that sees his minutes reduced, which was also the case at the start of last season under Lamps ironically enough.
Livramento has 12 months on his contract, maybe he wasnt planning on staying anyway, after seeing Lamptey leave because of James, who knows whether he wants to stay.
Hakimi is class, and will improve us if we manage to pull this off.
