Wetrat, I see that all your toons are 100+ laff. It seems to me that you should have no problem dealing with smaller toons who may crash your elevator. On the other hand, you could also teleport to one of the many other districts available. Small toons are really only congregating in the factory in the most populated district. And yes, poor gag choices can be extremely frustrating, but this problem is by no means confined to lower laffers. For instance, only a few minutes ago, I finished a VP in which a 104 laff toon was using marbles on level 12's
I haven't found smaller toons being "out of area" to be much of a problem at all. It's all in how you deal with it.
