I also think her raspy voice would be very remincicent of Idina’s vocals, which might also be why Disney chose Demi to do the Pop version of Let It Go for Frozen."
I completely agree. Not only does she have the talent of acting through song, but indeed also the vulnerability that Elphaba needs. She also has the kind of confidence Elphaba has, which is very specific, almost trying to be self reassuring and urbane and humble, and in this clip posted above, she also has the witchy thing going on in the way she uses her voice at times. This video is basically the perfect audition for Elphaba.
