Impeachment will be for “treason, bribery, or other high crimes and misdemeanors” and Judges remain in office “during good behavior”.
There is no provision in the Constitution for removing Judges whose opinion (in the Majority) you disagree with.
Five of Nine SCOTUS Judges could not constitutionally be impeached because Congress disagrees with their decision.
Oh they can be impeached, all right. After all it just means "accused."
It remains for the Senate to convict and punish, but since the passage of the 17th Amendment, that step is almost meaningless, specially in the case where each party holds a subbranch of the legislature; and guess who has the final word as to the Constitutionality?
