A few pointers...
The majority of carnivorous plants require, or only look their best with full sun, or in this case; strong artifical lights.
Nepenthes do not like to be waterlogged, and require air to the roots.... bear that it mind when planting.... they will have to be in separate pots raised above the surface of the substrate.
Not all genera will share the same soil preference, some may not be suitable, or will not grow as well as they should. Again, separate pots would be the answer for the pickier types.
Drosera capensis and Drosera spatulata are veritable weeds as far as CP's go though, and will probably survive just fine!
I would add lots of tropical Utricularia's direct in the terrestrial substrate, as not only do they love to be waterlogged, they also grow quite easily in a standard mix of peat and sand, spread fast, and when they flower, the paludarium will look stunning!
For longevity of life in the paludarium, I would stick to easy tropical/mexican Pinguicula (butterworts), tropical Utricularia (terrestrial & aquatic), and easy tropical Drosera (sundews). Some of the hardier, more tolerant lowland Nepenthes (tropical pitcher) might grow well.
However, if you plan to suspend potted specimens catering for their own needs and only benefitting from the light and humidity of the paludarium (not technically part of the final display), then you can have any tropical really!
