I just had an idea for a story and I'm not sure how to go about it. So I thought I would post it in a group that handles story ideas(like this one) and see what happens.

Idea: What would happen if Luna was a changeling? Not just any changeling, but a Queen?

Background/additional information:
Luna has always been a changeling and has known it. She found ways to deal with the hunger while on the moon(i.e. Hibernating in a cocoon) celestia was not aware of this up until Luna's return from her imprisonment where the elements of harmony revealed her to celestia. But not the mane six. Not many complications arise until the canterlot wedding. Where all is revealed

Has anyone used this? If not, I'd be interested.
