The above can be fixed by software for condition 1. and some change in circuits around the column cutout for condition 2
How these changes are made is likely to remain confidential until approved to ensure the impartiality and integrity of design changes.
Time will tell, think it won't be much longer as the earliest time it takes for these stages to complete is coming towards fruition soon.
With respect, fulfilling your condition 2 would obviate the stated purpose of MCAS which is to increase apparent stick force required to 'pull up' in certain parts of the flight envelope. If PF can pull back on the stick and cause MCAS to cease operation then the purpose will not be achieved.
If 2 is required then another solution to the flight instability (which is not instability) will be needed
