I would love to see Klaus and Mikael interaction because it was right at the end where Mikael realised he screwed up and there was some regret in his eyes, so it would be nice to have seen Klaus and him interact on the other side.

Indeed

There will probably be a collaboration between them in the future after some of them are resurrected and reunited, Finn, Kol, and Rebekah along with Dahlia, Esther and Freya interact in the distant future as some of them want to recover their lives as witches and Esther is the only one who knows how to undo vampirism without the need for a cure? Are the rest of them Klaus, Elijah, Mikael, Hope and Hayley the only vampire and hybrid part of the family that remains that way for the physical protection of their clan? I believe that in the distant future they will come together in this way since some endings indicate peace between them and the possible continuation of them wanting to be witches will generate a number of powerful witches in the future, I think they will possibly reactivate witchcraft in the Mikaelson clan.

Great thought although Klaus will likely remain a hybrid if he were to be resurrected but yeah it will mostly likely be more peaceful family reunion if it does happen. (It won’t happen unfortunately)

Possibly it will happen because the plot of the entire series is unfinished business between the characters which always results in them being resurrected to confront and resolve these issues, but as there is always someone who thinks that only your opinion is relevant, like your case, I didn't ask you if will it happen or not, I just pointed out situations that lead to this due to three of them with major interaction problems having found peace after that there is nothing stopping it from happening in the distant future, after all they found peace do you know what that means? apparently not, right?

Jesse-cool theory but I don't know if vampirism plays a part in peace.
