I'll agree with the idea of Reala behind an uncoated '30's lens as a good way to go as well it certainly is one of my favorite combinations... OTOH, your Nikon & Kodachrome will probably get you there as well as anything.
It seems like a difficult assignment; perhaps you might do well to consider having multiple formats along and seeing which works best at the light table/photoshop screen?
