I’m not sure Congress can regulate the Supreme Court’s voting rules, but I agree with your first point. We should’ve done that during the Warren court and stripped the Court of jurisdiction to challenge law on social and moral issues.

Without the Warren Court's decisions in Brown v. Board or Cooper v. Aaron ("separate but equal" schools), we likely would have had even more race-related social upheaval in the 60s than we actually did. Robert Caro's books on LBJ recount how he (LBJ) had to work very hard and skillfully to get civil- and voting-rights legislation past decades-long Southern congressional blockades — Southern committee chairman, plus Senate filibusters — and even then it was a near-run thing.

Without SCOTUS- and Fifth-Circuit intervention — back then, the "Mighty Fifth" was far more liberal than today — desegregation would have taken years longer, maybe even decades. The race riots and other violence we saw in the 60s (which I remember very well from childhood, including living in a Washington D.C. suburb during the riots after MLK's assassination) would likely have been even worse.

For its internal purposes the Court can certainly make any voting rules it wants. But I'd submit that Congress has the power (under the Exceptions and Regulations Clause) to limit what external effect is to be given to Court votes that don't rise to a congressionally-specified threshold.
