Well Smackdown got a great wrestler in Benoit last week, so that *somewhat* helps in replacing Angle. Now seeing as how Raw got the franchise John Cena in the first week, Smackdown would need to get something similar in return, so they should pick up someone like HHH and/or HBK in order to balance out the big names on both shows. Sending over Batista would also be pretty good for Smackdown and would solve the title situation (if HHH loses at Vengeance), but I would keep Batista on Raw until the next year's draft since there are still many matches he could have on Raw.
Also, send Taker over to Raw since he is getting old on Smackdown (as well as in real life
), and I think sending Edge over to Smackdown would be cool as well.
