I hope she gets the big seat someday.

That’s not how it works in the US.

Edit: In many other countries the most senior justice becomes the chief justice by seniority, and I was saying that’s not how it works in the US. But it looks like there have been four times when an associate justice has been “promoted” to chief justice, which I didn’t realize. The first being John Rutledge in 1795 and Rehnquist being the most recent in 1986.
