TNA is having pretty much every knockout compete inside a steel cage at lockdown. i'm not sure if beyond lita vs victoria, that wwe would even risk putting two talents in a cage, let alone the entire women's roster.
personally, i can't wait to see the match, since i think TNA's women's division is outstanding at the minute and can hopefully get better and better.
as for kong, at the minute, the way TNA are booking her is as an unstoppable force. i think if she's going to lose the title, they will only feasibly take it away from her in a triple threat match at the minute.
if they bring in some more talent in this division, the like of sarah del ray or others, then potentially they could reach a situation where kong loses cleanly, but until this monster push stops, i can't see her dropping the title by being pinned by anything other than a roll up
