If you still are having a good flow, which I dought, I would put them in a nuc, remove the queen excluder, add a frame of brood and a frame of honey if you can spare it from another hive, put in an entrance reducer (1 1/2" to 2" opening), and feed the dickens out of them.
You can always combine them later if they are not doing well.
Just too many choices .
Good luck with them and let us know what happens.
