What roles could the remaining contestants on The Glee Project play?

Here's what I think:

Lindsay - The girl that gives Quinn a run for her money in popularity,
and becomes rivals with Rachel in glee. I could see her trying to date
Puck or Sam.

Cameron - Obviously, the nerd. He could like walk in and no one would
expect him to be able to sing well, and then blow them all away. I
coudl see him dating Quinn.

Alex - He's a mash-up of Kurt  Mercedes. I think he could play the
lead singer of another rival school's glee club.

Marissa - The girl who just moved to Lima from like Los Angeles, and
thinks she's the best at everything.

Samuel - The guy who just got out of rehab, and is looking for
redemption through joining the glee club. He might compete with Puck
to be the "bad boy" of the show.

Matheus - He could be a big surprise for the glee club when he joins,
I could see him trying to date Santana, but constantly failing.

Hannah - She could also be self-concious about her appearance, and be
found in the bathroom singing by like Rachel or something, and then be
asked to join glee.

McKynleigh - She could play Figgin's granddaughter who gets everything
she wants.. including all the solos in the glee club. She could
compete with Mercedes for the diva of the group.

Damian - Definitely a foreign exchange student from Ireland. He just
moved to Lima with his parents, and found his big break by joining
glee. He might want to date Rachel.

Emily - The new cheerleader who joins the glee club under Sue's orders
to make sure Santana, Brittany, and Quinn quit glee, since they
betryed her. She might try to date.. everyone. Lol.

BTW: My favorites are Cameron and Lindsay!!! :)
