I'd rather have a mass swap. Pick five housemates to go into the secret house, and only one can come back, along with four of the new neighbours.
That way we get George's replacement, and we can get rid of four current HMs at once.
Let's say, and I'm just thinking off the top of my head of course...

we could maybe ditch, I don't know, Lea, Richard, Susie and Aisleyene?
