Hm, I can hardly imagine a scene less conducive to domestic bliss than if we were to move in and leave the others in Grimmauld. Come to think of it, we could all move to the Manor, the place has something like 30 bedrooms - more if you count the private apartments and guest suites. I remember getting thoroughly lost once when we came for her engagement party. We could move the entire Order there.

But somehow I doubt she'd take well to us importing all our Muggle compatriots into the Manor. And I doubt Draco would want to come back without Hermione. We could simply not give her the choice, of course, but if we're going to invade, then we should consider locking her in her apartments so we don't have to see her.
