Yeah, queens will very seldomly move into an empty y-tong nest unless it's a single-chamber one.
If possible you could however fill all but one chamber with sand(Or moist sawdust might work for a wood-dwelling species) that can be excavated later, this'll make the nest smaller, and a queen -might- be comfortable enough to move in there. Still no guarantees.
