It sounds like you have several choices that would work.
Your choices are either to move a big group of teenagers into the silkies at once... That will mess up the pecking order, any everyone should be fine....
Or you can turn the tables on the established ones.... For example I might put the rooster and bossier hens, or the entire established flock into a chicken tractor (or that stall you mentioned)for a week, and put the young ones into the regular coop. The young ones would have time to get familiar with the coop, and learn where things are and feel a bit at home, then I toss the old chickens back into the coop.
Either way, your nankin should be a good flier, and your silkies should be terrible fliers. Put a couple of higher perches in the coop where the nankin can go hide if the silkies bully her. That should also help take care of any problems.
You are correct though, putting just two youngsters in with the older crowd is much more likely to end up with problems.
