Second, is she talented enough in the ring? Well, I can't say whether or not, as I haven't watched any of her matches, but Velvet Sky and Madison Rayne aren't the female HBKs and they work extremely well in that aspect of TNA, so why not? Von Erich has wrestling in her blood so she might work well.
With the addition of the Knockouts Tag Team Championship, they really need all the new women that they can so they will be able to spread the division out evenly. Considering that the Beautiful People still worked as a trio instead of just a duo, I can't see why they'd have a problem adding Lacey in and teaming with Madison while Velvet focuses on the Knockouts title itself, as she's the more over of the two. The only problem comes if Lacey is a pain to deal with behind the scenes and/or if she cannot wrestle to save her life. In the meantime, I'm going to stare at this picture some more.
