Myself, I would take one frame of brood and bees from hive one and leave it in a new hive where hive 1 is located and move hive one to a new location. Let the single frame and the field bees release the new queen. (slow release) The remainder of hive 1 will do fine without field bees as you are the field bees by feeding.

Give the virgin in hive 2 time to prove herself or not.

I do not know how long it takes for a hive to develop loyalty to a new virgin, good question I've never seen answered.

I think it is easier to see when it does not happen. Going LW is more of an evolution than a revolution. There is always 1 to 3 % LW in a healthy hive from what I read here. So it is more of, when does a hive attach it's loyalty to the Laying workers rather than a proper queen. It does not happen at the end of a split, or out to 35 days or so, give them brood and they will typically try again. Mating nucs can have at least one miss without going LW.

The trigger event, loss of a laying queen, is usually a missed event by the keeper, or it would be a quickly cured event and not result in LW.

A hive suddenly going LW, as often quoted, not likely true.
