I still think the best option is to go in hard for Kimmich. Have him play right back most of the time, stepping inside into midfield alongside Rodri (with Akanji, Dias/Stones and Ake/Gvardiol making a 3). And he can fill in for Rodri when needed.
That for me makes more sense than looking for an understudy who is never going to be anything other than a significant downgrade on Rodri - and for that reason, will only very rarely be trusted to replace him anyway.
