Emergency queen cells are unlikely to be optimal. First out will likely be a scrubby queen developed from a ‘just-young-enough larva, not the best way to do it. With only half the colony, the multitude of queen cells are not likely to as well nurtured as a few cells in a strong colony.
Regarding the weather, you should know that the UK has a maritime climate. A good climate but lousy weather. The middle of April is just plain hopefulness in most parts of the UK.
How many drones were about at that time? I could predict that the weather is likely to be unfavourable sometime in April/early May. Why do you think there is such demand for queens from distant lands? Just think about it. UK bee farmers/breeders would have loads of queens available - if they could - but they know that conditions are not good for queen rearing (the proper way) early in the season in the UK, let alone a walk-away split.
Guessing about the weather is simply a lottery. Far better to wait that extra month and improve the probability of success. Given time, you might learn to think before trying to ‘jump the gun’.
