"Evening News:" What about Ted Koppel?

Now that the jackals of the press - me! - have poor Katie Couric out the door, we are left with this inconvenient question: Who, ummm, will replace her?
I pondered that briefly this morning, while putting a few nails in the coffin of "Evening News," but here's one suggestion that occurred to me (or rather a friend more thoughtful on these matters:)
What about Ted?
I speak of Koppel, who disappeared into the bowels of the Discovery Channel two years ago and has been in the witness protection program ever since. (No, really, he's done a bunch of thoughtful documentaries, and remains pretty much in the game.)
What about Ted? Has anyone called him. Do they know what he's thinking? Is he on ANYONE'S radar at CBS? There are advantages (and disadvantages, perhaps) and I lay them out now:
1.) He's the right demographic. That's right - white male of advanced middle age. Rather elderly people watch these newscasts, and they sometimes prefer same in their anchors; sometimes, but not necessarily, with Brian Williams being the obvious exception.
2.) He's got that anchorly mien - the voice, the eyes, the head, the hair. It's a compleat anchor package, if you will, but not a compleat Ron Burgundy blow-dried anchor package.
3.) He's done it all. Ted is embued with almost exactly 30 years of big-league-anchor-experience; "Nightline" was birthed during the Iranian hostage crisis, and he didn't miss much of a stride over those thirty years (though he had plenty of experience, at State, and elsewhere at ABC News.)
4.) He could come cheap. No $15 million anchor man here! Pay his production company a million bucks a year, and all he has to do is read a telePrompter every night for a half hour (plus another half hour for the west coast feed.) I don't think Ted is greedy, honestly. (I don't think Katie is either, but ...)
Disadvantages:
1.) He's not off the CBS News farm. This is important: To be hugely successful at CBS News, one must have spent the vast bulk of one's career there; there are a couple of exceptions (sure, Mike Wallace worked for ABC back in the dark ages), but for the most part this holds true. CBS News has a unique culture - to a certain extent, it is bottled up and walled off; David Burke, a one-time news president and transplant from ABC, once told someone he couldn't understand the place - there were metaphoric walls everywhere that he didn't know how to get around. He didn't last any time at all. CBS News is not kind to outsiders - that's just the way it is - and Ted would be an outsider.
2.) Ted probably wouldn't want to do it. Yeah, he'd be flattered to get the call (he ALWAYS is), but at the end of the day, he's got a great life - plus, ego stroking gets old - and he doesn't need the camera like others who shall remain nameless. CBS has come after him before - he once told someone (I forget who) that he'd never work for Larry Tisch. Could he work for Sumner and Leslie?
Okay, that's all I've got for now. Four advantages versus two disadvantages - maybe someone at CBS SHOULD think of Ted...
