No meter that I know of takes reciprocity failure into consideration. Different films have widely different reciprocity characteristics. Ilford's website has reciprocity data on FP4+ in the film data pdf, but I'd recommend doing your own tests to get the exposure/development balance right for the look you want. Reciprocity failure hits the shadows more than the highlights (as you probably know) so compensation development may be required - depends what you want.

Some slow films become effectively faster than 'fast' film when long exposures are used, because of their superior reciprocity characteristics. It's those lonely-heart silver atoms pining away, waiting for a mate so they can survive an hour instead of a fraction of a second.

I very much like Tom Cooper's pictures of the sea at night. There were made with exposures of a few hours.

Best,
