So many Dark Elves and they can't give me a different bride choice... Kinda mad about that...
On topic: Doubt you can do that. If you have Hearthfire you can tell her to leave and go live at her house then try to get her to come to the house in Solstheim, but I doubt it will work. Kinda an entirely new continent so it makes sense that she couldn't come with you.
My character is crazy, Muiri is good for him.. So bad that we can't live in Raven Rock...
There's a (great) house in Raven Rock, with full crafting amenities and an enormous master bedroom, with a special bedroom for followers, but no children's beds.
