If you were to book a Title Unification

[The Naitch]

Which WWE Champ and WHC Champ would you have feud together, and how would it play out

[Anybody Thrilla]

I'd have The Undertaker dethrone Batista and keep the title all the way until Wrestlemania 25. I'd have John Cena keep his title for just as long. Have the match at WM25.

[thedamndest]

Undertaker Vs. HBK at WM25 in a Hell in a Cell. My reasoning is that it would be the end of the brand separation, and to merge the rosters you would build the show around returning to a previous era, AKA 10 years ago. Or something.

Didn't TNA already do this when they gave Kurt "Broken Freakin' Neck and Roids" Angle every single title they had?

'The Animal' Batista versus John 'Superman' Cena

[Mercury Bullet]

John Cena vs. Batista tomorrow night on Raw, with Cena winning.

[Jura]

Have the 2 champs argue backstage at a PPV about who's better. That leads to chaos with both champs appearing on both shows and Vince strips both of the title then declares that there will be a tournament to see who will be the 6 to enter the Elimination Chamber and winner of that will be the Undisputed Champion. Of course the 2 former champs will be among the final six.

'The Animal' Batista versus John 'Superman' Cena
Honestly Batista vs Cena is the most logical way to go. They are (pushed as) the biggest things on their respective brands and, storyline wise, it would be a huge match.

Though MY vision would be Cena vs. Undertaker at Wrestlemania, Title/Streak vs Title.

[The One]

Actually, Cena has his own WrestleMania streak.

I'd book it as Triple Threat at WrestleMania...

WWE Champ John Cena vs. World Champ Batista vs. ECW Champ Mr. Kennedy (he wins the Rumble and then picks up the ECW Title at No Way Out)

Not a great match, but certainly one that would make the most sense from a booking stand point.

[Bad Company]

Surprised at how many people want to see Taker unify the titles, but he was my first choice as well.

I would have him beat Kahli.

Or Cena v Undertaker, and have cena beat the streak.

[Mercury Bullet]

Seriously, if they were to re-unify the titles, I would want it to be to elevate an "up and comer" and be somebody's first title reign. The first two names that come to mind are Kennedy and MVP. I think there should be a three-way match (like ToVo mentioned, but minus Kennedy holding the ECW title, the ECW title doesn't matter, anyway...) three way match with the WWE Champ, WH Champ, and Rumble Winner at Wrestlemania. (Rumble Winner = Kennedy or MVP) and the rumble winner goes over in the match.

[Mr. Pierre]

I'd book it similar to Vengeance '01 with a 4-man tournament.

The 4 participants would be the WWE Champion (Cena), World Heavyweight Champion (Undertaker), ECW Champion (CM Punk), and the 2008 Rumble winner (Mr. Kennedy).

There would be 2 matches earlier in the show to see who advances to the main event for the "Undisputed Championship". You could see some fresh matches with those four guys, and it would make for a fun ME scene.

I disagree. Not because it's a bad idea, but I think they should put it on an established star making whoever beats him bigger, which is why I think Taker could be the best bet. He doesn't hog the title and he can almost always pull a good "sports entertainment" match out of someone.

[Theo Dious]

Honestly Batista vs Cena is the most logical way to go. They are (pushed as) the biggest things on their respective brands and, storyline wise, it would be a huge match.

Think about it, they were on the cover of SD vs Raw 2006 and they're champions with the 2008 version coming out soon.

[BigDaddyCool]

I would some how work it out to have Shawn Micheals unite it.

[BigDaddyCool]

Or have MVP do it, he looks good dripping in Gold.
