Yes, antibodies could adapt to mirror pathogens. The concern is that the system which generates antibodies wouldn’t be strongly triggered. The Science article says: “For example, experiments show that mirror proteins resist cleavage into peptides for antigen presentation and do not reliably trigger important adaptive immune responses such as the production of antibodies (11, 12).”
