Hello HennyPennyChick..when my Echeveria Nodulosa got too leggy one time, I decided to cut off the top part but kept the remaining stem still attached to the mother plant. The top part I let it callused first and stuck it back to the container since there is space for it and I know the media is very well draining. It was in late Fall then, and I kept the plant outdoors, positioning it nearer to the house, so it gets reflective heat at night. Later on as our city trees have gone dormant for winter, then I positioned it to more sun. It is winter time anyways, so even if it gets direct sun, it is still nicely cool around. I can do that here since we have mild winters, no snow, just occasional rains. If you're in snow country, then your option is just to overwinter it indoors by your sunniest window and delay pruning to Spring.
Later on as the seasons change, you have to position it back slowly outdoors, to acclimate again and move again to part sun/shade, especially if your area is like mine where we get into onerously dry and hot conditions for the next 7 months.
For now, you may have to delay pruning your plant to Spring, since it will naturally slow down if grown indoors during winter time. To prune it now and grow it indoors takes a lot of energy which the plant is just not inclined to do, with light levels weaker, and duration too short. Just stake the plant for the time being, wait it out. It may even attempt to grow new babies anywhere up and down the bare stem. Be careful with watering, once or twice a month is more than enough during the cold season.
