TCPSocketProxy as input argument in module

I am writing my own (android) module and I wanted to pass an initialised TCPSocket to my module, but I don't know how to do this. I was thinking as follows:

In js, the usage of the module:

var tcpSocket = Ti.Network.Socket.createTCP({
    host: Ti.Platform.address, 
    port: 40401,
    connected: function (e) {...},
    error: function (e) {...}
});
 
var myService = myModule.createService();
 
myService.setSocket(tcpSocket);

and in the java module myModule:

@Kroll.proxy(creatableInModule=myModule.class)
public class ServiceProxy extends KrollProxy{
 
    @Kroll.method
    @Kroll.setProperty
    public void setSocket(TCPSocketProxy socket) {
        this.socket = socket;
    }
}

Does anybody know how to do this? Is it allowed to use native objects from titanium in your own module?
