Do you mean that you would somehow 'trick' the sensor into sending the same signal it does now at higher flow rates? Why would you ever want to do that?
The MAF is a Mass Air Flow sensor - it corrects for changes in air density due to humidty, altitude, and temperature to give an accurate measurement of the mass of air flowing [Kg per minute, etc.] in order to meter the proper amount of fuel through the injectors to maintain the correct air-fuel ratio.
If what you mean is to physically increase the flow by removing restrictions, etc. then there should be no problem as long as you do not exceed the range of air flow that the MAF sensor was calibrated for. Not all sensors are universal - many have upper and lower limits, too high or too low and you will not get accurate readings.
The MAF is one of the crucial inputs to proper fueling of any engine - it would be the last thing I would ever mess with.
