Next Glinda ?

Now that it is official that McKenzie Kurtz will leave Wicked in march, do you have an idea of who could be the next Glinda ? I was thinking Allie Trimm as she is the current standby and a lot of fans like her. What do you think ?

Ps: i am really sad that McKenzie is leaving she is my favorite Glinda of all time, i think she was the best Glinda since Kristin Chenoweth
