I don't understand what you are getting at with the scenarios you are presenting. Even if a party abolished and re-established itself after each election, they would still only be able to appoint a portion of the judges equal to the portion of the vote they received. Similarly, having multiple affiliated parties wouldn't provide any benefit because voters would still ultimately have to split their votes between them. The proportion of the vote that the affiliated parties is unchanged. I'm not particularly concerned with how many of the judges are replaced after each election; as long as the end result is that the judges reflect the political makeup of the country. Even replacing all of the judges every election would be better than the current situation where Republican judges could control the Supreme Court for decades due to lifetime appointments.
