trans | Call for readings

I have another request of the community at large. My beloved Erica and I are getting married soon, and need to find a couple of readings for the ceremony. I'd like to find something trans-related, by Bornstein or Feinberg, for instance. That seems unlikely, so I'm also looking in various pagan texts. I don't have any interest in mainstream stuff, but would consider things in the Gnostic Gospels.

Any one have a suggestion?
