Like nudging the sampling rate up or down to better match what your
working with?

If your concern is moving the RF frequency in fine frequency steps then there should be no need to do this. You can tune the transmit and receive frequencies with arbitrary precision.

If your concern is moving the sample rate by significant amounts in order to be an exact multiple of symbol rate, then some people have done this by replacing the main oscillator. A lot of people using OpenBTS use 52 MHz, for example.
