As Loki says it's not a bad offer, but you're better off standing pat.
1) Rest assured Nabokov won't be back. He's signed long term in the KHL now, and as Radulov has discovered, it's not easy to break those contracts. Rumours of threatening one's family if you do.
2) Keep Hiller. He is the starting goaltender on a good team. Fleury is injury-prone and I don't think the Coyotes will keep up the pace this year so Bryz may suffer.
3) As much as I like Kane, Malkin is superior, especially in a severely limited keeper such as this one. Malkin had a down year. He'll return to his glory this year, and you would be sorry to have traded him away.
