Is that clear enough about why Squid cannot do anything? Squid can change the cert issuer from X to A or X to Y. But cannot make any specific issuer A or Y known when it is not already known** by the client. ** intermediate certs that can be D/L by the client can be considered "known" when (and only when) their root CA is already trusted. Unless the client does not download missing intermediates.
