Sibling names too matchy matchy?

So I have a one year old daughter named Arielle and expecting a son at the end of April. My husband and I cannot agree on a name to save our lives! However, we were looking at names on a website earlier and we saw the name Samuel and we looked at eachother with a spark in the eye. That was it. Until I thought about it and how weird it would be to have Arielle and Samuel... Even if we called them nicknames (we call our daughter Elle/Ellie) and Samuel will most likely get called Sam/Sammy I’m still not sure. Opinions?
