I don't like the not-so-thinly-veiled insult at the divas.
How long will Beth be out for? The Smackdown Diva's divison has enough gas in it to continue for a few months before she returns. I can't decide whether or not it's a shame that the WWE introduced a replica Women's Title for McCool to hold (rather than just let Layla hold the belt by herself). Layla being the champion could have made for an interesting storyline with McCool slowly becoming furious that Layla has HER title, while Layla feuds with Kelly or Tiffany. They could feud over who is the true champion somewhere down the line, before Phoenix returns.
So there's two (or three) feuds. Kelly vs Laycool, Tiffany vs Laycool and eventually McCool vs Layla. Sure, there won't be 5* classics but Layla, Michelle and Tiffany are capable of having decent to good matches (and Kelly is not longer abysmal).
Gail hooking up with Evan Bourne recently is the best thing to happen to her since returning to WWE, so I don't want her to move over to Smackdown if Evan stays on RAW. I think it's the first case of a man being paired with a woman to help the woman get over rather than vice versa. If they both moved over to Smackdown that could give both an opportunity to shine, so Gail is a possibility.
Seeing as Serena is a heel it wouldn't make much sense to have her enter the Diva's Division at the moment.
There aren't really any other face diva's that can be moved from RAW to Smackdown with much success, nor are there women who can be turned from heel to face.
Bringing AJ Lee up from FCW is another possibility. The girl's got some skills and is good looking so that's two out of two.
Of course, Kong would be a great signing for WWE. It would be fantastic to see her run through the diva's, and if she gets to the top of the division it's a perfect return feud for Beth.
