Have I screw up again?
You made more work for yourself. You didn't need two empty boxes on each hive to start. I would still separate the hives from the original position by 10 ft to make sure the foragers are going to the queen right side. That only needs to be for a day or two.
Lets talk hypothetical, if you did as I said you would have two hives 5 boxes high. The next day or two you would see where most of the bees went. The less populated hive gets the box you put on taken off.
Decision time...
If you want more hives you divide the populous hive again. If you don't want more hives you take another box off the populous hive and put it on the other. Then you will have to observe again because you could have transferred the queen.
My choice would be to split again and then start combining to the least populous hive. There is likely to be queen cells that you could use to start nucs or do away with. I would lean toward making the nucs in case one of these hives ends up queenless. You can always shake them out.
