The suggestion of the OP if adopted would be another bullet shot into an important organ of SCOTUS. Soon, people would be put on SCOTUS as soon as they are 18 after a chip is put in their brains to control their reasoning.
The Supreme Court functions less as a judicial body these days than as a hyper-partisan House of Lords. It sucks, but that’s the way it is. Blame the Republicans if you don’t like it 
They stole one seat and put an attempted rapist in another. There is nothing about the Supreme Court today that merits anything like the sort of special institutional credibility you seem to believe we should afford it.
I sometimes wonder how many body blows the civic culture can absorbed with everything caustic and hyper partisan where we all distrust if not loathe each other, with SCOTUS taken down as well in the dyspeptic tsunami, before the rule of law and the other load bearing foundations fall away, and hope I am not still alive to witness it, if that is our destiny.
This forum is reflective of what is out there, and indeed what is out there is considerably worse. I find it sobering and sad. Good luck.
