***Roberts would have to die, resign, or be impeached by the House and convicted/removed by the Senate for that to happen***

By my reading of the Constitution, I see nothing about the appointment of the Chief Justice chair that designates that it is for life. Roberts would remain on the Court just not as CJ.

Playbook.

All judges are appointed for life including the Chief Justice. You’re reading the Consti8tution incorrectly.
