To be honest, the guest host thing is a welcome break from the GMs. That's not to say that they are bad, but we've seen all of the possibilities, faces, heels, inadequates and wrestlers booking themselves. When the guest host thing ends, it may be worth going back to that idea, but I actually think that it may be interesting to have a faceless board of directors in charge. There's no point in having an on screen GM if there's no conflict with them, and that really isn't happening. Orton and Jericho are the only ones that interact with the guest hosts and it's fine, but I don't think Orton can maintain a long term feud with an authority figure, which is why about 500 people were brought into the McMahon v Orton feud. There's no need for a regular GM unless they are involved deeply in angles, and that hasn't been the case for quite some time, to be honest with you.
