WWE Wrestlers who could be a part of Game of Thrones 

Vince McMahon and Tywin Lannister are secretly friends

Rich men are ruthless in both Westeros and WWE.

Just as Stephanie could easily be Cersei Lannister, her father, Vince McMahon is basically the real-life version of the Lannister patriarch, Tywin.

Tywin flexed his muscles because he was richer than the all of the kingdoms combined in Westeros.

He was ruthless and did whatever he wanted to because his money could buy anyone and anything. Although he despised one of his kids, Tyrion, he still considered him part of the family and expected him to act accordingly.

Mr. McMahon was an evil character ever since the late 1990s and the Monday Night Wars. He even kidnapped his own daughter once. Seriously. And let's not forget the time he and Shane challenged God and Shawn Michaels to a wrestling match. Who does that?

But due to their status as the richest family at the party, they pushed around any and everyone they wanted, even if it meant getting whacked by their kids (like Twyin got from Tyrion on the crapper).

Rich men are usually the same no matter when or where they are throughout time and in what reality they come from.
