RAW workflow incl. stabilization and slo-mo while still grading from CDNGs

[lechatlisse]

Hi there,

I have been shooting ML RAW for a big lingerie company and I need to nail a workflow for post. I am a little confused as to the best way to proceed.

I need to achieve the following:
-Make selects and edit in Premiere Pro (with 12bit CDNGs, since they play perfectly in PP)
-Slow down some of the footage using a good tool (optical flow via Twixtor or similar built-in tool)
-Stabilize the footage using the Warp Stabliizer
-Grade in DaVinci from the original CDNGs, so that I am grading from the RAW footage (ideally reconnected to 16bit CDNGs at this point)

Since I can't send Warp Stabilized footage to DaVinci (or, I'm guessing stabilized footage either), would those steps have to be post grade?

I would be very grateful if someone could help me figure out a solid workflow that maintain the best quality at every step.

Thanks!
