To be honest, what the WWE Divas division needs is not their own show. What they need are three things, in my opinion: decent story-lines (thus leading to some actual face time), decent and diverse characters (as opposed to the very limited collection of "female-appropriate" characters we get these days), and rougher matches (with maybe a few foreign objects thrown in for kicks.) The reason most people don't care about women's wrestling is that the female wrestlers don't get the story time and face time of the male wrestlers, primarily. An audience has to actually care about the actual characters in order for the matches to be consistently interesting, and if you don't build a story out of the various characters, then nobody's going to care about them.
Likewise, you have the problem of comparing females to males in terms of power and given the booking, not just of wins but of matches in general, there's no comparison. The general brutality we see with males as opposed to females in the WWE, even when the females fight each other, is like day and night. The female matches look like "cat fights" by comparison. It's not that the ladies can't do it, it's that they're held back from doing it so they don't outshine the men, who are considered the money makers in the company. So, while women are restricted to singles and tag matches with traditional rules and (in general) staying within the confines of the ring, the men exit the ring more than once a match, use whatever blunt object is available, and get occasional access to cages, ladders, tables, etc. The general message being sent here is that the females are "too weak" to handle wrestling at the level that the males do.
Divas having their own show could work, but only if these matters are addressed first and foremost. It might actually work out given that they'd no longer have the males to compete with for face time. Diversifying their character types, however, is a definite must. While a roster full of swimsuit models might be considered great *********ion fodder for teenage boys, it doesn't make for a consistently interesting show. You'll need diverse character gimmicks as well as diverse types of women. Someone like Kharma is a good start...but we need more.
