On a flow with no brood to feed, a nuc box fills up remarkably fast. If it is mostly the honey which you want, you might want to consider putting out a full sized box. Perhaps even a double deep.
You could put your queenless nuc sized colony, with large brood frames, into the bottom of a double deep. Set that out and forget about it for 4 to 6 weeks. Assuming a good flow period through that, When you go back to it there will be either: a nice queenrite hive full of honey or a nice laying worker hive full of honey. Either way, you will have a harvest.
