You would be surprised, these low light plants are pretty hardy, you won't be pruning every day, but they should survive with very little light. I think java fern grows in the dark.
Worst case scenario you try a couple of species that don't work and scrap the idea and go with fake.
My personal favorites that grow well for me.
Anubias Lanceolata
Anubias Nana narrow leaf
Bolbitis heudelotii (african water fern)
Crypt Lutea
Ruby melon sword
Guppy grass
Both Mgamer and Customdrum in the classifieds have very nice low light plants for sale, as do others. Heck, next time I cut my stuff back I could send you a few.
