Will Gratton Claim Stop Another Trade?

"Center Chris Gratton has been claimed off re-entry waivers today by the Columbus Blue Jackets."

I wonder the claiming of Chris Gratton will affect Columbus' (alleged) pursuit of Jeff Halpern. It might be good for the Lightning to trade him away, especially if they are able to get a decent return, ie. Jakub Voracek or Derick Brassard. It might be difficult to get such a high return for Halpern, but it would be good for the Lightning if they were able to.
