Gasol is a too good a player and one of the few assets the Lakers have. They're going to want a lot for him.
I don't think they'll find a match unless they take on salary longer term though. Just as the C's had to eat some salary to deal KG/Pierce, its incredibly hard to find a match that doesn't have longer term salary ballast.
It will be interesting. A lot will depend on where the team stands in February. If they are clearly a lottery team, then I could see them try to get what they can for Gasol. Their top priority might be to try to move him along with Nash, to get Nash off the books for the summer.
What could be really interesting could be if a team like Washington to make a run at the pair.
Something like this for Washington:
http://espn.go.com/nba/tradeMachine?tradeId=lawpw93 The Lakers get rid of Nash, and get a couple young players to add to their even higher lottery pick this season without Nash and Gasol messing things up.
Washington gets an All-Star big man to put next to Nene, and a great mentor for Wall, who can also slide in at the SG spot, and cover the opposing PG, because Wall is big enough to cover SGs.
That is the type of move that could make Washington a real team to watch in the playoffs this year.
