We don't need more Justices like Scalia and Thomas, nor more Justices like Ginsburg, Breyer, Sotomayor, and Kagan. We need more Justices like Oliver Wendell Holmes, Benjamin Cardozo, and Hugo Black. I think if people like them were nominated, then the Senate would confirm them without controversy.
I doubt it. If Trump's next appointment was the another Hugo Black, he'd get voted down close to unanimously. Neither the people who voted for Trump nor the people who voted for Clinton would find him acceptable.
Black should be posthumously impeached for his decision in Oregon v Mitchell
