I’ll take a crack at this.
I haven’t opened an entire household to one planetary influence before, but I assume that success would lie in making the entire household an inviting environment for the planetary spirit to visit. Perhaps keep charged sigils of the Moon in every room, let the moon’s favorite incense into every room, have mirrors by the windows to reflect moonlight into the rooms in the evening?
Also, I suggest keeping some sort of moon talisman on each family member. It is said that selenite, named after Selene the Roman goddess of the moon, was once regarded as rock that fell off the moon - maybe a piece of selenite can be carried around by each person, or kept in their rooms.
Maybe also evoke the moon, and tell it that you want its influence to flood through the house indefinitely.
The only pitfall I could see would be the imbalance it might create from having the moon be such a strong influence in the entire household. I haven’t had that happen to me, but I would imagine that it won’t be so terrible if that happens. Who knows, it might even turn out better than expected.
Keep us posted on the results. I’m curious to see what happens.
