Ideally, yes, but once you've become accustomed to the various chores of attending your plants, you'll likely tire of checking the water levels every day and draining the terrarium when you accidentally overwater it.
Sundews, bladderworts and many butterworts prefer fairly wet soil during some or all of the year. Most of the ones you'll begin with come from bogs or meadows where the water table comes nearly to the surface of the soil. Nepenthes, on the other hand, recieve relatively equal amounts of water all year and grow in airier mixes. They are watered by daily precipitation and their roots are rarely in contact with standing water for any extended period of time. Obviously, there is a conflict of interest here. There are some varieties of Nepenthes that live in wetter conditions - I think there's at least one species that lives in boggish conditions specifically and is fine with wet roots. But you'll need to do your research to find an appropriate plant. It will probably be easier if you just make a little hill in the back of the tank for your Neps and fill that with a good, airy mix for them. It will be less trouble than you think. Or you can just sink the pots that your Neps come in into the soil - that way they can easily be pulled free in the event that they don't take to your conditions.
I grow all my Neps in two terrariums with dried LFS on the bottom, about an inch thick. There's some live LFS, aquatic bladderworts, and Drosera prolifera running loose in there too. My Neps are in pots, resting on jar lids and small tupperware containers, so that they're just about at the water line of the terrariums. I water them mostly by misting them daily with a spray bottle. When enough water accumulates, the water line touches the pots of the Neps and the excess water is wicked into the growing medium.
I'm hoping that, over time, the live LFS and other things in the terrarium will grow tall enough to hide the base of the pots and give it a sort of natural look, like pots resting on the ground. I can post a picture later if you're interested in seeing how it works, but only with the disclaimer that my plants are still recovering from my roommate caring for them (or not caring for them, as it would be) over the week that I went out of town.
If you can find it, get a copy of Peter D'Amato's "The Savage Garden." It has everything you need to know to get started. Also, there are some websites you should take a look at. Barry Rice's CP FAQ is an important read, and there's a good primer on Nepenthes in his 'FAQ Library.' Take what he says lightly; Barry can be a little disparaging at times but I've never gone wrong with his advice. Neps Around the House, Neps for Everyone, and Nep University are all good reads by experienced forum members, with indices of the various Nepenthes species to help you choose appropriate plants.
