OK, so it's clear that the SC - a bunch of hyperpowered geriatrics that pretends to be unpoliticised, even if they blates ain't - is getting a bit crazy. The only reason anybody likes the Court is that they are less embarassing than Congress, which isn't the world's most ringing endorsement. So here's my idea to fix it:
1) Justices have 18 year terms (not term limits though, incumbent justices can run again. This introduces some accountability, without being to mad (i.e. kicking people off the bench when they're actually pretty good nominees.
Fixed term is a good idea, however I'm against Justices running for reelection, as it would led to them to politicize even more out of purely electoral concern.
