I hate to be "that guy", but you can't create optimal conditions for both temperature and humidity for a nepenthes bical in that space. If you were to create good temp and humidity in that space, the bical would outgrow it in weeks. It's a vining plant.
But, theoretically speaking, N. bicalcarata is found at elevations of between 0 and 700 meters.
This range equates to temperatures of approximately 29 - 34°C (83 - 93°F) during the day, and 19 - 24°C (65 - 75°F) at night. Those day temps are not really suited well for a desktop dome. Nepenthes generally like it humid. I target 75% RH during the day and 95% at night (although I grow highlands more than lowlands).
For cephalotus, optimal temperatures in summer during the daytime are around 77-86 degrees Fahrenheit (25-30 Celsius). But they can also survive hotter days, with temperatures ranging from 90-104 Fahrenheit (32-40 Celsius). To make matters worse, cephalotus typically enjoy colder winters. The temperature in winter ideally should not be higher than 68 degrees F (20 degrees Celsius). Ideal temperatures are between 50-68 degrees F (10-20 degrees Celsius). In comparison, bical does not enjoy colder winter temps.
At best, you might be able to keep both of the alive for a few weeks while using a seedling heat pad to increase the temp some.
