I just recently hit 60 dwellers in my vault, and as soon as I did, there was a group of feral ghouls that attacked me.
Now I've read that when you get to "X" amount of dwellers, the difficulty increases such as different enemies attacking you. But what happens if I start banning dwellers from my vault to get it below a certain number?
Do the rooms I built that require a certain number of villagers automatically get destroyed? Will the new enemies still spawn and attack? Does the difficulty decrease?
Right now most of my dwellers have very low stats, even when I have armor equipped. Currently I have a male and female dweller training their stats, my ultimate goal is to have 10 on each stat then start breeding for better dwellers.

Apparently, you can ban a bunch of Dwellers to fall below the threshold where these attacks start occurring to get them to stop, as seen in this answer:
As for whether rooms will become re-locked if you drop beneath the required number, it looks like they will not, according to the same answer linked above.
