Calling a child by 2 different names?

My husband is dead set on naming our sin Leon. I'm not completely in love with it, but if we do name our son Leon, his middle name would be Lucas, which I do love. Would it be too confusing if my husband called him Leon and I called him Lucas, and then maybe everyone else can call him by whichever? Then once he's older he can decide which he prefers to go by?

I follow Jamie Otis on Instagram (from married at first sight). She loved the name Gracie, but they named her Henley Grace. Jamie calls her Gracie and her husband calls her Henley. I kind if thought it was strange because I had never seen anyone do that, but now I'm considering it lol
