We know there are probably better options out there.
But the situation here is like: I want to achieve something like ... and this is my current camera, a 6d.

With 40fps you lose the standard Canon liveview, and recording times are probably less then 10 seconds, more like 5 seconds I guess.
And with the use of a gimbal to smooth things out, I should definitely stick with standard 30fps, so you keep good working live view and don't need to use the crop_rec module.
I never used HDR, but I doubt if it is worth the trouble in post proces, especially on the 6d.
The 6d has very clean shadows compared to the other Canon DSLR's, and raw recording gives you plenty of dynamic range.
I see you're using Lightroom to edit the DNG's. I like Lightroom too for my photo's, really easy to use and I achieve best looking colors in Lightroom.
But for raw video(with lineskipping), it's not that good. Magic lantern raw video in Lightroom gives lots of false color moire, plus you are losing much of the fine detail in Lightroom.
Colors and exposure and noise reduction handles all really good in Lightroom, but it is very bad in keeping fine detail.
What you could try is import the DNG's in RawTherapee, do a basic exposure and white balance adjusment, set LMMSE as debayering, maybe activate the defringe option, for all colors (see the youtube video) and export it as 16 bit TIF files.
Now open these TIF files in Lightroom, and do further adjustment.
So your basically getting best of both worlds, better debayering and less color moire from RawTherapee, easy to use interface and good color and noise reduction from Lightroom.
