family name

So my husband is Richard Tyson the 3rd. I'm struggling because I think it would be super cool for our son to be Richard Tyson the 4th. There's not a lot of 4ths these days. But I really don't like that name. Haha. I would definitely call him either Tyson or Ty. Nothing with the Richard name. Don't like that for sure. We already have 3 Richards within both of our families. What would you all do?! Keep the family name going or be that one in law that breaks the tradition?!
