I don't think you'll have any problem with a Miranda inside the house next to a relatively sunny window.
I've had a sangunea for years indoors. I tried misting it daily, or putting it next to a humidifier. It could care less. I had it next to a bright window and thought it wasn't getting enough light, so when it got warmer I put it outside. It got burned (guess it got used to the indoor light levels).
is a good website for what you're trying to do (although it hasn't been updated in about a decade it appears). Overall most nepenthes are pretty hardy. Especially the common hybrids.
