the bigest problem would be with the different rules, the only way to do such a shared universe is if they create a story who has this feature integrated since the very beginning, as example: naruto-verse chars cant exist in the same verse as bleach chars, and the same with toriko and one piece, or world trigger and hst or Boku no hero academia and other verses,

IF they story was solely based on a few chars and the other world was completly the same THAN it would be easy, unfortunetly manga/LN/anime-storys tend to use a complete fictional verse :( I'm talking just a shared Naruto Universe. Not a shared Shonen Universe.
