Review Detail of ProcrastinatiMeem in Overlord: Administrator's Vacation

What are the options?

Waifu or cool guy. Choose.

Will the main girls of the original will be part of the MC's Harem? (Albedo, pleiades, etc...)

.. .. .. .. .. .. .

The question, is how?

Super chapitre merci de faire une histoire différente ou ses pas un MC avec ainz.

The way to do so would be for the MC to take over Nazarick or to dirrectly change the setting of the NPC with an item (admin available one?). For taking over Nazarick I see three ways : 1 - steal the guild weapon and use a world class item to become its new owner, using it to forcefuly change the target of the NPC' worship to the MC. 2 - have Nazarick appear into the new world without Ainz or any other "suprem being". The MC could have had some "bond" with the original members of Nazarick, making him known to the NPC. It would lead to them choosing to serve him. 3 - The MC using a backdoor to a system that allowed admins to change ownership of a guild and its base when the preview' guild master hasn't logged for some time.

Albedo H-ntai.

just toss a coin, both are good

Why not both? Waifu and cool guy if it's the MC you're planning on adding. just use ai for it, maybe like a power couple picture of them.
