The Constitution says almost nothing about the how the Supreme Court should be constituted or even how its members be selected, only that we should have one. I don't see how any of its language precludes it sitting with existing higher court judges on the bench on a per-session basis.
Hell, at least that'd guarantee they'd be real judges, unlike the attempted Bork or for that matter Amy Barrett.

That's an awesome idea, but I think it'd require a constitutional amendment to change. So that's not happening.
Doubling down on your hypothetical, though, also have a second set of those judges selected who will decide on what cases go before the court.
So you don't have the people making the ruling the same ones deciding on which cases to rule on, and which ones they don't.
