It is what it is. They're just cousins. It would be different if they were siblings

If you are at all close to your nephew and his parents, I would avoid this. I do find it too similar.

My daughter name is Cairo and my nephew name is Kiryn. When I was pregnant and we decided on that name I didn't even realize how similar they were until she was born. Oh well.

I pressed no but i like

Not strange but could get confusing and annoying at family gatherings. My mum and my cousin have the same name but they are called Big and little followed by their name , so its never been confusing.
