ESPN: "Sonics chairman Clay Bennett is so eager to sever ties with Seattle that he's willing to leave the team's name, logo, colors and history behind to avoid a messy divorce." - If this turkey feels he must move the team the least he can do is leave the name behind for the next team in Seattle.
As for the name of the team in Okie City, here's a list of Oklahoma State symbols(linked in the article above), you can also let your minds wander. What do you think of when you hear Oklahoma?
UPDATE: I'd go with Oklahoma City Wild Turkeys. This would allow them to do a marketing deal with Wild Turkey Bourbon; logos on the uniforms, Wild Turkey on the sidelines instead of water or Gatorade, and discounted shots at the game. It could be a huge draw!
