We used to do this years ago at my company. You have to find the various ProtobufUtil and RemoteException related classes, wherever the remote classname string is parsed from a protobuf into a Class. You need to push some custom code to rewrite the strings there. I think there were two or three spots where we shimmed in that code. I don't have any more specifics than that, because it was a while ago.
I don't think there are currently plans to add support for shaded class names, but it's an open source project so you're more than welcome to create a JIRA and even contribute to it. I don't think it's too hard of a task.
