Opinion number 1:
It takes a really strong hive to raise a good queen. And you won't have a really strong hive at this point with the packages you just installed. One option is to let the two starts you have build up strong enough to take bees and brood out of and start a nuc in your other hive box at a latter date. But I would still get the nuc a queen that is already laying. A laying queen puts a nuc four weeks ahead of one that has to make a queen.
