Anyway, backtracking a bit. A Crisis on Infinite Earths adaptation is exactly what is needed to put Earth-1 and Earth-38 into one universe, which would make future crossovers much easier.

Furthermore, it could also involve other Earths and their heroes. Jesse Quick, Harry Wells, Jay Garrick, and Gypsy all could get involved as well. (assuming they fix up the mess Savitar created of all the characters being on the wrong Earths).
