As for acquiring Kawasaki.. I would offer him a minor league deal. He says he'll take one to play for the Mariners. If hes valuable, you'll control him for a while.
Hes more athletic than Nishioka with a stronger arm, so its possible he could adjust defensively. You could give him some regular time at AAA initially for a feeling out processs.
Offensively, I'm skeptical but there is So Taguchi. Taguchi was basically the OF version of Kawasaki and ended up hitting better in MLB (in his decline phase no less) than he did in the NPB.
If Kawasaki could hit like Taguchi (his upside), he'd be quite valuable. No reason not to at least offer him a minor league deal to see if he can pull it off.
