I would do it, but under circumstances that would never happen. Those circumstances require one or two of Vinny, Umberger, and Grossmann heading to LA in return and/or LA eating a fair portion of his remaining contract.
edit: Carchidi would also have to greet Richie at the airport, get down on his knees and apologize for being a POS beat writer
As LA is looking into the option as a way to cut salary cap, it would make no sense for them.
As others have mentioned, Richie is a 3rd line center at best anymore, he's not worth that contract for what he brings. Hell, he was a 3rd line center when he left, usually centering a line of crap (Nodl, Carcillo, Versteeg, etc).
