I am curious. Have you tried using dark frame subtraction? Perhaps you'd only need a few dark frames per shoot.
I haven't had the occasion yet to try to perform the NR in post, but I would have imagined it would have been as simple as grabbing a dark frame at that start, middle and finish of a shot using a tool for this purpose. I would love to know if this technique would work as well as the built-in NR
