Oops! Sorry, RPCManager doesn't do what you need to do. As a matter of fact, with JGroups 2.3 multiplexer, you could have created a multiplexer stack and create your own RPCManager and then have both RPCManager and Cache to share the same channel. However, this process is not straightforward for standalone. I will raise an issue to discuss. Meanwhile, if don't mind to use separate channel, you can look into org.jboss.cache.rpc.RPCTreeCache. Basically, you can create a separate RPCTreeCache instance (a la TreeCache 1.4 style) and execute your RPC calls there. Keep in mind the class is deprecated though.
