Are these too similar for sisters? + BQ's?

Of your choices, I prefer Elizabeth and Eloise. I prefer Eliza or Liza and Ella. If you want to use Raine, I would use it as Raine. My niece is named Rain and for some reason gets the spelling Raine a lot in mail, etc... BTW... once you get pregnant for real, you will probably change your mind over and over. Mine did until the day my daughter was born. My husband vetoed almost everything! Good luck to you.
