What if there was a MLP:FiM version of the Broadway musical, "Into the Woods"?

This is how I would imagine the cast:
Spike-Narrator
Twilight Sparkle-Cinderella
apfel, apple Jack-Jack
Baker-Carrot Cake
Baker's Wife-Cupcake
Cinderella's Stepmother-Princess Luna?
Florinda-Diamond Tiara
Lucinda-Silver Spoon
Jack's Mother-Cherry Jubilee
Little Red Ridinghood-Apple Bloom
Witch-Trixie
Cinderella's parents-Twilight's parents
Wolf-Discord
Räpunzel-Fluttershy
Grandmother-Granny Smith

Any other ideas for who could be who?
