IF you do actually output or go back to film you can BB the internegative or realese print. However this would require even more testing and more dollar bills, but it could give you a really cool unique outcome. If you have the budget try it. Test It.
I think the best way is to shoot as clean as possible, get you're exposures perfect, Video doesn't recover from overexposure. And puling up the black levels reveals noise and a greyer rendition.
Then increase the contrast to your preference, and desaturate it accordingly. This should give you more freedom during color correction.
