I just tried by replacing ca_list file of my proxy (that contained ca certs of my peers) with a single bogus ca cert. Then I executed tls.cfg and made a call from one of the peers to my proxy. My proxy still recognized the call as coming from the peer based on its tls common name. My understanding is that this should not have been possible if the cached ca_list of my proxy would have been updated.
It turned out that the old tls connection from the peer to my proxy was still alive. After terminating the connection, a new connection setup was correctly refused.
So looks like certs can be reloaded on the fly. I'll try later with client and server certs.
