Victor Martinez for Jay Bruce and Mike Napoli?

So I've decided to try to trade for an everyday top catcher instead of alternating Towles and Napoli. I love the Astros and hate to give up on Towles but he is the worst hitter in baseball right now and is destroying my team. I have good OF and could trade Napoli and either Jay Bruce, Curtis Granderson, Nate McLouth, Jason Bay or Matt Holliday. V-Mart's owner is finicky and it will take a lot to pry Martinez from him. What should I do??? Thanks my brothers.
