I believe she could form a group with the girls there. There's enough talent and all of them are pretty. I don't know why she feels the need to do more looking. She just needs to pick the right girls out of what she has.
I remember watching Making the Band (Danity Kane) and Puff had to work with so much less the first season. I remember watching with my bf at the time and saying "I don't really like any of them, except Aubrey and Andrea. Then Puff said the same thing. He took Aubrey, Andrea, and another girl and kept looking.
He needed to keep looking, but I don't think Kelly has to... But, I guess, it could just give her a bigger pool to choose from. So I'll see.
