I have to say, I really like the idea. I always thought it was kind of ironic that that song is so popular, because when you really think about it, the message of the song isn't really what the movie is trying to promote. She's singing about being herself and forgetting everyone else, and rules, and everything, but the point seems to be that that is NOT the way to go about it. I mean, look at what happens when she just decides to "be herself", she freezes the entire kingdom and puts others in huge danger. She can't just simply be herself, she has to learn to care about others as well. Although at the same time, she can't just conceal it all, she has to find a balance. Which is why I think she could have very easily been a great villain, as someone who doesn't care about anyone but herself, and just "letting it go" so to speak. Sorry if this makes no sense, just my random ramblings...
