Godzilla to Giants?

An interesting rumor is Mastui to the Giants for Matt Cain or Tim Lincecum. Matsui is an all-star and a very good player but a big part of his value is how he opens up the Japanese market. If Matsui is traded could signing Fukudome be next? I think Fukudome could replace Matsui very well. Cain and Lincecum are both studs as well. Especially Lincecum. Matsui has a no trade clause so obviously this could be nothing.
