No, but Rogue led during Claremont's Revolution run. And she was one of the younger members of the X-Men at one time. I figured the logic of having Kitty lead was the same as having Rogue lead during that run. It's a change-up to what's expected while still using the more familiar characters. Granted, maybe she should be struggling with it a little more or someone should suggest that she's overcompensating for her inexperience by barking orders like that.
