I'm not using 3.x yet but just to provide some feedback, what you're  
doing looks reasonable from my reading of the documentation. I do see  
this in 3.1.0's commands.c though --

         /* SECURITY PATCH - disable these for the time being */
         switch(cmd){
         case CMD_CHANGE_GLOBAL_HOST_EVENT_HANDLER:
         case CMD_CHANGE_GLOBAL_SVC_EVENT_HANDLER:
         case CMD_CHANGE_HOST_EVENT_HANDLER:
         case CMD_CHANGE_SVC_EVENT_HANDLER:
         case CMD_CHANGE_HOST_CHECK_COMMAND:
         case CMD_CHANGE_SVC_CHECK_COMMAND:
                 return ERROR;
                 }

That's in the right section and my reading of the code is that it does  
exactly that; prevent changing of those values... Maybe it's something  
being worked on in the development branch?
