Should be pretty simple, open her up in the GECK I think her race would be in the first tab. Edit: Make sure to back up any files before you mod them, I learned that one the hard way.
I find OWB has a lot more personality(No pun intended.) than the other DLCs for NV, Mobius alone nearly had me wetting myself. The large(and interesting) new worldspace is also a plus. All in all, it's totally worth the caps.
