A Champion Family?

So we have a pretty diverse champion roster, but there's still plenty of themes/types of characters we don't really have yet. We have some pairs of siblings (Garen and Lux, Katarina and Cassiopeia, Darius and Draven) and a pair of young lovers (Xayah and Rakan), but there are still a few familial relationships we don't have, like a parent and their child.

That by itself would be an interesting dynamic, but what if it was taken one step further and we were introduced to a whole FAMILY of champions? There are five roles in the game, and each member of the family could fill each role. There'd be the father, the mother, two children (son and daughter most likely) and then maybe either a young child or a family pet. They'd all function well on their own, of course, but they could also play really well together for like a five-man premade. I don't really have any specific ideas for their personalities or what roles they'd play on a team, but I think it'd be a really interesting dynamic to have some kind of super-influential family on the rift together. We don't have a married couple at all, nor do we have any parents with their children either. This set of champions would be an answer to those niches all at once.

What do you guys think? What kinds of things would you want to see from a family of champions like this? I'd love to hear people's thoughts!
