[Discuss-gnuradio] Capturing 12-bit data at 10MHz sample clock?

This may be a dumb question, but suppose I changed the USRP ADC clock to 10MHz. Would there be a way to get 12-bit integer data across the USB, using usrp_rx_cfile.py or something similar? This would result in a manageable USB transfer rate of 30MB/s and line up pretty well with the bandwidth of the TVRX tuner.

From poking around, it appears to me that the data transfer across the USB is either 2 * 8 bits/sample or 2 * 16. 2 * 12 should be easy enough to disentangle?

Just curious,
