[DPB101]

Add or subtract the number of justices. Limit appellate jurisdiction. Maybe some other things. Turn off the heat in the winter and A/C in the summer?

U.S. Constitution
Article III
Section 2

In all cases affecting ambassadors, other public ministers and consuls, and those in which a state shall be party, the Supreme Court shall have original jurisdiction. In all the other cases before mentioned, the Supreme Court shall have appellate jurisdiction, both as to law and fact, with such exceptions, and under such regulations as the Congress shall make.

[Consort]

The Senate can impeach/remove Supreme Court Justices, but you will never see them impeach and remove five of them at once. And you will likely never see them do any the things you mentioned.
