Get creative. Use some chopsticks or manipulate a clothes hanger or two to make a corral of sorts, then wrap cling wrap around it. Put a hole the size of a dime or quarter on top and and few holes a little smaller than a dime around the bottom. Bam, humidity tent. You can then mist a little through the top hole to instantly up the humidity and you will have a small amount of air circulation to prevent stagnation. I agree, you could remove some leaves from the bigger one, especially if a half a day in the dome doesn't perk them up.
