The processor in your camera is not the only thing you need to override for your proposal to work. Consider the focus system, the iris, and the shutter system, and their respective upper and lower performance boundaries. What you are suggesting appears to be a design up idea not an after it was built idea. In other words you need a whole team of engineers at Olympus at your service to redesign the camera from the ground up. The exception may be, some engineering hack that allows for the higher frame rate perhaps through the firmware.
I am not clear on what you mean by changing the ISO and shutter speed while shooting, do you mean change the ISO or shutter speed in the same take? If so, I've never heard of any camera being able to do that, nor do I understand what you are trying to get?
