shadetree reduction of the o2 sensor output is a good idea but im not sure it will work as intended. as the exhaust wont have double the o2 if 2 cylinders are deactivated it will likely have a higher ratio as o2 is burnt up in combustion of the o2 in the working cylinders.
There might be a good way to do this with a wide band o2 sensor (mine i assume is only a narrow band) but the ideal way would be to ensure the deactivated cylinders dont exhaust into the section with the o2 sensor.

Also i have no doubt some incorrect opinions are on this thread but thanks to all that have contributed even if they are wrong. Ultimately id like to test things out and actually see what happens but until i can test its good to see all the possible angles. The ideas that have come from this thread have given me some good direction
