you could trim the tops, which would cause the bottom shoots to become more dominate. it would also casue them to grow out more side ways. however probably the safest bet is what they said above, take out a few plants. if you have the space out in the back yard, you can place them out back. however, you will want to "harden" them off to the outdoors. for that you will need to have a spot that is mostly covered by the shade.
for the first day, i would chose a day or time where it is overcast outside. i would take out the plants you have selected and place them by your back door outside - if it has some shade. i would only place it out there for an hour or two and then bring them back in. i would also leave them by a window / door with windows so it can continue to recieve day light. the next day i would take it out for about 2 hours in the shade. and rinse and repeat. by day 3 or 4 you will want to take it out into direct sunlight for an hour or two and then put it back in the shade. at the end of a week, at the most you should be able to put their pots or transplant them in the full sun light. I had to transplant my Lao Village plants outside as they did not seem like they were doing all that well indoors. even with that i took clones and brought them outdoors.
