I would strongly suggest she work within the system she's got. We try to tell girls this over and over again, but if she has a group of friends who want to start a sorority and there's a sorority that is struggling for members, if they all joined that sorority both problems would be solved. That is of course assuming the sorority WANTED all those girls, but I think you get the point. A small chapter can change its persona pretty quickly with the addition of a handful of strong pledges. And being too good for any of these excellent sororities is short-sighted.
If you want to build your reputation as a leader among Panhellenic circles, work on that. If you can play a role in achieving parity at this campus that would be something to be proud of.
