I like Norah with Elise, or Eloise better.
I have a feeling you'd constantly be saying "Norie and Elsie" or "Norah and Elsa" when referring to them both because it would be hard to switch the /uh/ and /E/ final sound. Not a deal breaker, but just something that popped in my mind as a teacher that does that to kids in small groups all the time.
