I'd get it ! Love what Marvel are proposing with the new X-Men series and Fearless Defenders.
My choice for the founding team would be:
Hawkwoman (Shayera Thal)
Supergirl, Batgirl, Miss Martian and Gypsy as trainees
I imagine Huntress and Power Girl would go over to Earth2 eventually (they can guest star frequently as would Big Barda, Fire and Ice)
