Could Cavs pull a sign and trade for Chris Bosh to keep Lebron?

I think if they offered Jamison, Hickson, West, and 1st round pick they could get Bosh and both teams benefited. Cleveland would have a top 8 guy as a 2nd option to Lebron James. Toronto could still be a playoff team and they could attract other big name free agents if they are a contending team because they have been unsuccessful in rebuilding their teams since most of their draftees do not stay there such as Vince Carter and Chris Bosh.
