I think the issue is packing SCOTUS isn’t even a band aid fix to the problem. You’d have to completely overhaul the way the Court works to get a meaningful impact on the way it operates currently. I’ve seen ideas floated like expanding the judiciary and then choosing a certain number of justices randomly to preside over each case, but that is probably worse than our current system because you could end up with an even more radical Court presiding over a very impactful case.
