I plan on scanning emulsion side (we'll see how that works) at at least 1080p resolution (we're adapting a camera to make it work), so it should have a pretty good picture.

Sorry to be a little late to this party. I saw your color corrections and wondered if you'd describe your methodology.
I've been trying to work out an approach (with details beginning here on msycamore's THX 1138 thread) based on an analysis of the problem of film fading. The re-expansion of the faded color "compressed ranges" consistantly produces good results. It always amazes me just how easy and precise it is (an "eyedropper" helps for the colors' numbers):

Each chart shows the corresponding R-G-B compression spread and the settings for new beginning points of 0 on the low end, and 255 on the high. Other settings (gamma, midtones) can further fine-tune to counter-act the non-uniformity of the fade.

I hope you will also document, in detail, the equipment and software and approach of your custom transfers. With lots of pictures, too! :)
