Could Ekko have Lunarian blood?

I am basing this purely and only one the fact that he is the only person I've seen in piltover/zaun that has white hair. I defer to you guys if it can be a thing.

I dont think this is the intention of his original design at all, but given how alot of the truth about his canon parents is still a mystery in Arcane, can this be something that could possibly be a thing if they wanted to go that route?
