Maximus Nuka Madigan

Second pregnancy, lost our first baby boy at 20 weeks late last year. Our deal was that my husband picks the first boy name and I pick the first girl name. He’s set on Maximus Madigan because “it’s the best superhero name” I love the name but we found out early with sneak peak last time and called him Max the whole pregnancy. We just found out again with sneak peek that we’re having another boy and my husband wants to keep Max because he always had the name attached to his future kid not so much the bump in my belly. I definitely associated the name with both and feel a little weird about keeping the name. Like it feels like we’re just replacing him, so I wanted his middle name to be a tribute to his big brother up in heaven. Did a bit of research and found out that Nuka means “younger sibling” in Greenland and thought it would be cute. Do you guys agree or does it sound too weird? Also if anyone has any suggestions I’d love to here them. Uso and Veli are also names that peaked my interest for meaning brother, but I think Nuka’s a little cooler. We also both play video games and know some people would get the Nuka cola reference, but still think it’s cute enough for a middle name.
