Nadia Van Dyne was introduced as Hope van Dyne.

I don't think they would introduce Nadia van Dyne in the MCU because she was created basically to be the comic version of Hope van Dyne as Hope herself never existed until the Ant-Man film. She is the daughter of Hank Pym, the partner of Scott Lang and the second Wasp, I guess they could say that Nadia is Hope's sister or cousin and show up as the Wasp on the Young Avengers but i am pretty sure Cassie Lang is going to become Stature in Quantumania and take the Ant-Man/Wasp role on the team

^ yeah i dont think its gonna happen either. She’s a very small role and u already have Cassie coming. Doesn’t seem necessary to me
