Megan would be great in numerous roles on Broadway. I would steer her far from anything "Karen-esque" and I think she would run screaming from anything described to her as "you know, like you did Karen." Megan is very deep and drawn to darker works. She actually would probably been a great choice for 3Penny, as she loves Weill and Brecht.
She just recently played here in Buffalo at the Unviersity's Center for the Arts and she has definitely been working with vocal coach. Her voice was powerfully strong and she hit the back of the theatre with her ending on Danny Boy. Not a dry eye in the house. She's also non-chalant. She came out in jeans and a tshirt for her performance. I think she'd be most at home with something grittier and less flashy, camp, or glam. Especially if she is trying to diversify.
She did mention her talkshow, so don't look for any new shows for her. She's tied up right now.
