If it were done right, then yes, it could be a good idea. Maybe Morbo's people could invade Earth, and Morbo would be fired from the news in case he was biast towards the invaders(!).
But on the other hand, sometimes I think Morbo (and Linda) works best in short doses of a few seconds/couple of minutes. He comes in, reads the news, threatens to destroy humanity, Linda laughs, and that's the end of their part of the episode. They do their joke, and that's it. They are like Scruffy, only there when they are needed.
But I've voted yes to this poll anyway.
