I don't see the win for the WWE. Sure, they can claim that they have "gay" wrestlers on their show, but it would still be in question as to the authenticity of their "gayness" as it is scripted programming. What you are looking for would best be suited for a wrestler to come out in public forum as authentically being homosexual. Even at this point, the likelihood of it taking place would most likely occur after said athlete's career; coming out during their career could be damaging for the probability of being cornered into a specific role that couldn't be broken from. I'm pretty sure Chris Kanyon had this same problem which is what he claimed to help segregate him from the populous of the WWE locker room. Once it was known that he was into men, it seems as if his downward spiral leading to his tragic suicide began acceleration into his life’s final plunge.
Sure, I can see what you are saying in theory, but I don't think that "faking gay" on a television show known for its outrageous storylines would give the desired result you are looking for.
