Why Hasn't TNA Made Sunny A Knockout?

Sunny & Chris Candido

If TNA wants to capitalize on WWE rejects why haven't they offered a job to Sunny? I mean she was the original Diva, and she has been out of work for like a decade now. She is clearly desperate. She was the hottest thing in wrestling for a few years, and was caught in the middle of a behind the scene feud between her boyfriend Shawn Michaels, and Bret Hart who she had an affair with. It cost Bret Hart his marriage and ended her relationship with Shawn Micheals and I think ultimately helped lead to Shawn screwing Bret out of the company. Only problem was Sunny quit with him. Regardless, Bret didn't want her so she went back to her old boyfriend Chris Candido in ECW until he died on an aneurism on a plane. He had surgery and  the doctor told him he would be ok to fly immediately afterwards, but a bubble went to his brain and killed him. After that she married a cop and disappeared for years. That is until she divorced him and tried to hire former ECW star New Jack to murder him. What a story. Anyways, she was a huge star in WWF, WCW, and ECW. She made a brief one night return to the WWE and still looks almost as hot as ever. Why hasn't TNA made her a Knockout?
