What should we do if Cordero leaves?

So now that free agents are free to talk dollars and cents with any team, I thought we should run through a list of things to do if Cordero walks.  Listed, in no particular order (I used ERA+ and WHIP both because I was in a bit of a hurry and they're what I was most comfortable using in a hurry)

1.Sign Eric Gagne.
His second-half numbers this past year were horrid, but he's got a career 124 ERA+ and 1.13 WHIP. Doug was talking about getting him at the deadline last year, and I have no doubts that he would have fared better in Milwaukee than he did in Beantown (how couldn't he?), and he might come a <span style="font-style:italic;">tad</span> cheaper with what happened last year.  At the very least, he'd be cheaper than Coco (Jon Heyman thinks he'll make $6M next year).
2.Sign Octavio Dotel.
He declined his option and filed for free agency. He also had a poor second half, and may not be the ideal closer, but he'll come cheaper than Coco or Gagne, and has a career 121 ERA+/1.24 WHIP.
3.Trade for Brian Fuentes.  The Rockies are apparently willing to shop him for a starting pitcher, something we happen to have an excess of. He's got a career 124 ERA+ and a 1.26 WHIP, though is (I think) under control for just one more year, so we could trade and extend him (maybe).  Or let him walk and get draft picks for a departing closer (again). He was a Type A player in this year's Elias Rankings.
4.Trade for Washington's Chad Cordero or Jon Rauch.
Apparently the Nats are looking for starting pitching and are willing to move Ryan Church as well. A package for both Church and Rauch/Cordero?  Rauch has a decent career 115 ERA+ / 1.22 WHIP. The "other" Cordero comes in at 154/1.19.  Plus, we wouldn't have to get rid of Coco's old uniform- we can just give it to Chad.
5.Trade for Scot Shields
This might be the one I would be most in favor of, but would probably be the hardest to pull off.  I am sure we'd have to give them at least one big prospect, and I dunno what else, but it would probably take a lot, especially as they signed him to a contract extension earlier this year.  Larry Stone notes that Chone Figgins could be made available if the Angels get A-Rod.  He has played some outfield, so maybe a big time deal involving Figgins and Shields?  I don't see it happening.
6.Trade for Akinori Otsuka.  We know that the Rangers were interested in Tony Gwynn, Jr back at the trade deadline, and it appears that they still have some interest in him. I'm sure it'd take more than just Gwynn, but I wouldn't be opposed to it (depending on who else is in the deal)
7.Other FA RPs of note: Eddie Guardado, Dan Kolb, Jorge Julio, Ray King, Jose Mesa, Bob Wickman.  Just kidding.
8.Convert one of our guys to closer.
It's been suggested maybe Ben Sheets convert to closer a la Smoltz/Meyers, but I doubt it would happen.  Dave Bush was a closer in college, and I wouldn't be against the move.
9.Or, of course, give the job back to Turnbow.

What do you guys think?
