Will setting the interpolation (sample rate) not suffice for your application?
usrp_basic_tx::set_fpga_tx_sample_rate_divisor()
or
usrp_standard_tx::set_interp_rate()

certainly the interp parameter can be changed in python easily.
Also consider the rational_resampler block if integer interpolation
rates do not meet your sample rate requirements.
