Doubtful, the write speed so far has been only 45ish mbps, for 4k raw, it would be only able to write 20-30 frames before buffer fills up and drops frames. Where have you seen tests on the 6D Mark II where the write speeds are only 45mb/s? The card slot is supports UHS-1, giving speeds up to 90mb/s IIRC. I'm not aware of any tests being done on Hello all , shot this yesterday @ 48fps then in After Effect I slowed down the frames rate to 23.976 & 12fps . Seems to have very good motion blur @ 12fps . Magic Lantern 2.3 has been released.

Firmware genius Tramm Hudson, who gave us the original Magic Lantern firmware, has released a new version that allows 5D Mark II owners to increase the video bitrate of their DSLR to 76MBps (the default is 38). This should make a world of difference in the battle against those pesky compression artifacts. Word on the street is that 76MBps is unstable, but the slightly lower 66MBps is working Magic Lantern is a free software that runs on a Canon camera to enable many new features in both video and photo mode. The current stable releases at the time of this writing are for: 5D mark II, 50D, 60D, 500D, 550D, and 600D. You can get the test releases for: 7D, 5D Mark III, EOS-M, 1100D/T3, and the 5D classic. This episode goes over the new Magic Lantern version 2.3. I will go over how to install on your card and basic features I use. Make sure you have the latest Magic Lantern Unified improvements I’ve been using the Magic Lantern Unified hack on the Canon 5D Mark II recently and it is now working very stably. The team behind Magic Lantern say that most of the features (like FPS override and focus peaking) were enabled by changing DIGIC registers… mlBzTL.
