Pronunciation of Delanie?

So my husband and I have a bit of a dilemma. We thought we had settled on the perfect girl name for our third little one, Delaney, until we realized we were pronouncing it wrong. We thought it was Dell-uh-knee, not Deh-lane-ee, and had planned to call her Della for short. We still love our pronunciation, and thought we would just change the spelling to Delanie or Dellanie, but everyone seems to just ume this is a unique spelling of Delaney. I've only found one example of someone who said their name was Delanie, "pronounced like Melanie". I don't really want her to have a "made-up" name, but I'm just sort-of stuck on it! I love it! Any thoughts?
