This sort of method is used in the Canon DSLR custom firmware Magic Lantern for HDR video - it brackets the exposure by ISO. However you have some problems with moving subjects: https://youtu.be/5me5jEr4ldQ?t=415 (warning - flashing images)
The issue is more with the dynamic range of the sensor than the ISO. Increasing the ISO would blow out the highlights long before providing sufficient detail of the shadows (not to mention the increased noise).
Regardless of this camera's performance the LIDAR and other sensors should have picked this up.
