I feel like maybe we could do something where, if it's revealed (or we believe) that the Earth-Prime characters are basically their former selves, we could say under the home universe section Earth-1/38/BL (pre-Crisis/formerly/something else) and Earth-Prime (post-crisis/currently/something else). And then for their bios, we can have a pre-crisis and post-crisis section (similar to original timeline and current timelines, where we could say that certain things changed as a result of the multiverse being reset during the crisis).

I am of the belief that the characters on Earth-Prime are the same as their Earth-1/38/BL selves, as there are some shots when J'onn was restoring memories that J'onn could not have been present for (like when Nash freed the Anti-Monitor and became Pariah). This leads me to think that he restored their memories from the alternate timeline (similar to how Cisco can see alternate timelines). However, as far as we know, J'onn cannot give a person someone else's memories.

Additionally, I do not think we should use "Prime" to describe anything not from Earth-Prime (such as the new Earth-2 being called Earth-2 Prime), mainly for the reason that only Earth-Prime is "prime," if that makes sense.
