Yea no... lol few problems. One... CFAST cards are expensive, very very very expensive. So you'll be needing A LOT MORE storage then if you shot 10 bit 4:2:2 Pro Res natively.
Two! As Adrian says, copy the media off the cards is critical. The cards just don't work well in that situation and if something happened, you may lose all your data. Plus, you'd be stuck grading the converts not the camera originals. I always keep camera originals, it's critical.
THREE... Taking Canon RAW and transcoding it to Pro Res 4:2:2 for editing (or another codec) is extremely time consuming. Remember, Canon RAW doesn't have the hardware support of RED Code or Cinema DNG, both which decode in hardware. Canon RAW does not decode in hardware, it's a software/CPU decoder. So when you use up your cores to decode, you have less cores to process and less cores to compress as Pro Res and DNX both encode using the CPU mostly. So transcoding Red Code and Cinema DNG is pretty fast, but you'd see maybe half of the speed on Canon Raw or any other Raw codec for that matter. Even Arri Raw isn't hardware supported in the same way sadly.
