I would start with pouch swapping between the two cages. After a couple weeks of that, then swap cages. Put the four in the pair's cage and put the pair in the four's cage.
After a week or so of that, I would do it on a weekend, take them into the bathroom. Also do it in the morning when they want to sleep.
Put the pair into the bathtub and take the alpha glider from the other cage and introduce that glider to the pair. If that goes well, take another and so on.
If the alpha causes trouble, then take him or her out and try another glider.
If it gets to the point where you only have one that you can't introduce leave that glider live alone for a week or two. I have found that they become more amicable to introductions after living alone for a week or two.
If all goes well and they go into a bonding
pouch together then which ever cage is going to be their cage, give it a deep cleaning. New fleece, scrub the cage and the wheel. Then I would put in at least 3 pouches
in case someone or more wants to sleep alone. You may find they will do this for a few days to a few week.s
Please keep us posted on your progress.
