Don't actually know how it should be done, take it how you will. Just throwing a few ideas out there.
Maybe have her mention them, saying "I'm not apart of THEM. I'm better than them.", even though it may be a stretch. Or just put her in as a female memeber of it.
Like I said, just throwing some things out there. Seeing a diva just go in and throw another one through a table would possibly get the crowd into it, just completely random.
Anyway, just trying to think up some ideas.
Why? Why do anything to something that's doing fine? A random barely legal british girl would kill the momentum. Is anyone going to believe that this tiny girl is in charge or associated with a giant Samoan, a mental patient and a train conductor? No, it's not believable. Jumping out of the confines of reality would be disastrous.
I wouldn't debut her for another year. She needs far more fine tuning. Her gimmicks is bland without a lot of realism behind. She has a lot of potential, but honestly, she could very well be the next Natalya. Talented, but not really used at all. Why rush her when she's not even ready?
Keep her in NXT for a while longer, debut Marie and Rae in about six months time, have one of them win the strap, and then debut Paige to face them. Having an actual diva or diva team to feud with would be the best way to get her over. Kaitlyn, Natalya, Layla, AJ are all pretty unique, not at all the typical image of a diva that Trish and Torrie perpetuated. Having her feud with them and being an 'anti-diva' would be stupid.
Summer Raw sucks, and she's 29, so WWE won't get a lot of milage out of her. Debut her, even if she's rather green, and use her annoying gimmick and voice and give her the divas title. Use her as a prop, as a tool to get Paige over.
Besides, I'm more excited to see Anya anyway. 6'1, legit kick-boxer background, and Russian. No that's a woman to get excited for.
