Thomas,
To accomplish what you're talking about, I think you'd just need to use
timed commands on both set_tx_rate() and set_gpio_attr(). If these are set
to execute simultaneously, the GPIO line you set will go high on the same
clock cycle as the LO retune.

Thomas,
I am looking at GPIO right now as well. As to your question #2 on examples, I
compiled and am able to run the example I found in the UHD software:
uhd/host/examples/gpio.cpp
I am able to set individual data lines to experiment with (and eventually use
as a roadmap for my development)
