I think what the OP is getting at, is can he scan proofs to get a reasonable approximation of what to expect from a darkroom print. And the answer is yes. But it requires a calibrated workflow. You can do a lot more in software than in the darkroom. And you will have to alter the scans in software at least somewhat to get an example of what you can expect in a darkroom. So the trick is figuring out how far you can take a scan in software, and still mimic that in the darkroom. That just takes experience and lots of trial and error.
Your best bet to start off with, is to make some acceptable looking prints in the darkroom with some under exposed negatives, over exposed negatives, and properly exposed negatives. Then scan those negatives into the computer. Now, create some presets that allow you to recreate the looks of those prints using those scans. Then you'll have some options you can use run through, to get a good idea of what's capable in the darkroom, just by scanning the negatives. You'll be able to tweak them a bit in software, as needed, to see test possible outcomes. But any major tweaks beyond your presets may not be possible. Only experience will tell you where you limits are, and what you can expect. And while it's not a perfect system, it should give you good enough insight into what's possible, and how difficult it will be to achieve your final goal, that you'll get a fairly good idea of what negatives are worth trying to print, and which ones aren't worth your time. Which, I assume, is what you're trying to achieve here.
