Other "normal-ish" spellings for Wren?

My husband and I are trying to decide on a gender neutral name for our angel baby. I went through so many lists and only ended up with 7 that I like. Out of my 7, Wren is the only one my husband likes, but he doesn't like the spelling. He suggested Rin, but I told him Wren is the traditional spelling and Rin would also change the pronunciation, which I don't like. I don't think there's any other way to spell it though that would keep the pronunciation and still look normal. I don't like when people take a totally normal name and give it an insane spelling, it's not something I would ever do and I don't want changing the spelling of Wren to be like that.
