Additional remark: I still think you should try my first suggestion,
because overall the config is much simpler But if for some reason you
need the setup like you tried already, you can trick mod_jk to use the
right worker:
worker.tomcatSSL1.domain=tomcat1
worker.tomcatSSL2.domain=tomcat2
cluster with HTTP/HTTPS connectors instead of AJP?

give you TC6 instances a new multicast address or port
