Can we get a Stance Dancer?

Before you say anything, yeah Udyr kinda fills that out but I'd like something more.

As it stands the closest we have are champions like Jayce, Nidalee, Elise and kiiiiiinda Gnar.

Aatrox's passive got me hyped when I saw the name but made me sad when I found out it was just an empowered auto.

I'd like ro see something akin to Gen from Street Fighter or Siegfried/Nightmare from Soul Calibur, where it focuses on switching quickly between stances to keep up a barrage of attacks.

Problen is how would you balance it, and how would you even make it work in a MOBA game without resorting to the Udyr method.
