zany idea: getting more bits resolution out of the ADC

The STM32F7 onboard DAC is only 12 bits.  I only need mono audio input.  Suppose I drive the left ADC input directly and the right from an op amp gain stage of say x16 and then combine the lowest 4 bits of R with left-shifted L?  Do I have something akin to a 16 bit ADC?  Should I diode-clamp the output of R so I don't generate overages to the ADC?
