Look into the games and media detection plugin to see how that's done... In 
ProcessKeys of your cOsdObject, you can return osPlugin, which calls the main 
menu entry of your plugin again. So, you can do the same thing in your 
MainMenuAction that is done in the code you posted. This way you can return 
completely different cOsdObject's than that currently in action.

Greetings,
