Kohn last name

Hi. My husband and I are trying for baby and we’re trying to figure out names. My husband is of ashkanazi descent and I am sephardic. His family is from Eastern Europe and had to change their family last name due to rising antisemitism back in the day (previously Kohn). Fun fact: His granddad’s tombstone in Israel has the last name “Kohn”. We would love to bring back “Kohn” for our kids - is it too weird/acceptable to use it as a middle name?
