To start with, the Yanks are moving Johnson to make room for Bernie Williams as DH, with Giambi playing 1B. So there is no logical reason for them to take on Konerko. From the Yankees point of view, it make no sense whatsoever.
Trading Maggs for Soriano would be difficult for me to do. I'm not sure Soriano is going to keep putting the numbers he has. I think he'll backslide some, and settle in at that level. Just call that a hunch. Trading Maggs, though, does open up the payroll situation. What scares me though, is if the Yanks offer Siriano and Weaver for Maggs and a prospect, I think KW will jump on it. I don't want to see that head case in a Sox uniform.
