What is the diameter of the hole in the middle of the nikor 4x5 reel? I wonder if the phototherm spindle could be made smaller diameter (it seems like it's a little wide, from just eyeballing the pictures). That might allow 12 sheets of 4x5 per run of the phototherm, assuming chemical coverage was high enough... ?

You couldn't rotate 12 sheets. They wouldn't stay in the reel. Too much dynamic drag on the film edge.
