Ooh, now that you mention it, I would add N. mirabilis to the list based on my own experience. Your temps might be a tiny bit low for it, but it might be the most vigorous and forgiving plant I have in my collection, ventricosa and ventrata included (of course your mileage may vary).
I got mine as an unrooted cutting from another member here almost a year ago and did *everything* wrong. I got the cutting and put it in the fridge to "keep it fresh" until I put it in water to root. I added fertilizer to the rooting water and used tap water instead of RO. I didn't put the cutting under lights for the first week. By the time I got everything right, all the leaves on the cutting had begun to turn brown and the stem was getting crispy. Yet still, a few weeks later, not only was the cutting producing new leaves and roots, it was pitchering already! Since then it has been going full-steam, non-stop.
