Are you at the wind up? Lots of bluff and bluster, I don't think any answer is going to be good enough here...
Also at the most the need is going to be for a 1:2 or 1:4 reproduction ratio (assuming a 24x36 imager).
It's worth noting that the reproduction ratio is irrelevant in terms of imager dimensions, all that's doing is cropping the projected image circle, the projected 1:2 or 1:4 ratio will be the same at the focal plane whether you are shooting on film, 135 format digital or APS-C cropped digital (or even APS-H digital)
The sensor crop is relevant in terms of effective angle of view, and this in turn determines perspective and working distance, and therefore depth of field, but it has nothing at all to do with reproduction ratio.
In practise this is less important these days for most users as digital cropping, large screen projection / high resolution printing can usually get you to where you want to be.
I'm struggling to think of any 'macro' lenses that will actually deliver 1:2 max these days, probably only the Canon 50mm f2.5 springs to mind. 1:1 macros are usually marked for 1:2, 1:3, 1;4 etc.
I think you are using a sledgehammer to crack a nut. We aren't doing drum scanning here, so you don't have to calibrate daylight film to flouro light, a grey card is all you need, shoot RAW and you can even play with it in post, at 16bit pull downs.
As for shadow noise, this really does ring troll alarm bells. QUITE LOUDLY.
Apologies if I'm wrong. Say hello to photoshop. Say hello to Adobe Camera Raw.
Your old way of working is dead. Set whatever you buy to adobe RGB from camera to software.
Calibrate your monitor.
Wrattens etc are dead.
If I've got you wrong I apologise. There are just some cues to your writing and archaic terminology that seems to be either trying to test our knowledge or expertise, or is at the wind up.
Maybe moderate your tone and you'll get more kindly moderated answers.
