well first thing id do is rearrange the rosters to make them alil more equal. there is literally nothing interesting going on in smackdown land. each week kurt angle rips off what triple h does from having a faction to being a mean heel for no reason.
I'd have a drift every year right after wrestlemania and this year i'd bring in a batch of recognizable guys into each show.
smackdown would have sting, ken shamrock, the sandman,and macho man - he never gets old
id switch randy orton out, because he has no where to go on raw anymore with having fueded with nearly everyone and isnt very interesting anymore -so a change to smackdown as well as a 5 month slow fued with john cena would be dope.
on raw i'd have edge christian trish and tomko make a canadian cliq that would bully everyone since evolution is about broken up. some how i'd bring brock lesner into raw and have him break people off as they set up a super match with him and triple h.
the title picture for raw would have ,edge, batista jericho and kane
smackdown i'd move cena, rvd, into the main events and kindly move jbl out
id pay what ever needed to be paid and bring jeff hardy back and have him and matt take over in the tag team area.
id bring back stevie ray and reform harlem heat with booker t
and the list could go on forever!
