Elsa as GL is very appropriate: Dedicated to good, compassionate, steady mind, strong will.



Anna as GL would be a different proposition. The ring also acts like a voice-activated/voice response terminal to the computers back at OA, and in the comics sometimes acts like a "living" user manual for the ring. When it comes to Anna, half the time, the ring would be saying, "Wait, what?", and "Well, wasn't THAT what you wanted?" the other half of the time.
